- Hey Donnie Smith here and welcome to my
DIY autobody and paint channel.
On this channel, we do body repair, paint cars,
you're gonna learn how to do some installs,
heck we're even working on a jet boat.
In this video, we're gonna show you how we made this jeep
look like this to this, using SEM bed liner.
Now this is the longer version but we're demonstrating
how to do this.
It's a little bit longer.
If you're wanting just the steps we took.
There's no demonstrations, just the steps.
We got a short version of this video.
If you go down in the description, there's a link there
to that video, you can click that and watch that.
And down in the description, we also have a PDF file
if you want to download the steps we took you know
such that you could print em.
So kick back for a few minutes and watch the steps we took
to bedline this jeep.
(circuits shorting)
and of course the first step is to clean the bed real good
and you're gonna do that using some soap and water
you know to wash the be out to remove the contaminants.
If you got a pressure washer, you can use that.
That works well but you want to wash it out
and clean it real good and then wipe it down with some wax
and grease remover, some type of cleaner to remove
all the contaminants, silicons and things like that.
Now we've already done that.
So we're gonna go ahead and move to step two
but don't forget this step.
It's very important.
And step two is to sand the surface that's gonna be bedlined
You can do this using 180 to 220 grit sandpaper
or you can get this bed liner brush like we have here.
We found this brush to work real well for this application
and we also found using a lower RPM, about 1000 RPM
on our polisher works the best for us.
Now on this jeep, we already have this primed.
We had this sandblasted and then we epoxied everything
just to keep it from rusting until we got to this point.
So this is primed but if you're sanding a bed,
Get that ready, you'd do it the same way
as you would sand that bed with a brush
or with the sandpaper.
Scuff it up to give it good adhesion for the bed liner
to stick to.
And step three, we're gonna scuff this
with a maroon scuff pad, a Scotchbrite,
and this is just to get all the hard-to-get areas
and the edges that you can't get with the sand paper
or with the brush, the abrasive brush.
And you wanna do this just to make sure that everything
is sanded well and has good adhesion.
If you don't have good adhesion somewhere,
you have a chance of that peeling
just like with any paint or finish process,
we'll always following the sanding with scuffing
to make sure everything is sanded good.
And after we get it all sanded and scuffed,
we are just gonna clean this out.
We're gonna blow with some compressed air
or you could use a vacuum cleaner to suck the dust out
but we need it clean so that when we go to masking,
you know the masking tape will stick.
If we're real dusty and has dust all over the place,
the masking tape is not gonna stick to the surface.
And step five, we are gonna mask the areas
that we don't want the bed liner to sprayed on.
There's quite a bit of over spray with this bed liner
so you wanna make sure that you cover everything up.
And see there's a lot of holes on this
and you may not have this many on a bed
but on this jeep we had a lot of holes.
And things like this gear shifter,
there's a trick to that we did not have any
but aluminum foil works well when you're goin up the poles.
Or if you're talking about like wire balloons,
things like that.
You can get some aluminum foil and just kind of squeeze
it on there rather than taping it up like this
because masking it up like this takes longer
and then when you go to unmask it,
it's a little more difficult too but we didn't have
no aluminum foil.
That's just a tip to keep in mind.
And then we just outlined the whole vehicle
where we're gonna break it at, the bed liner.
Basically on this, just the whole inside
is gonna get bedlined and so we have to mask the entire
outside surfaces off so we don't get over spray on there.
If we didn't, it's not painted yet, we'll be doing that soon
but it just saves a lot of time from having to clean up
over spray from the bed liner.
So we go around, outline the surface, you know,
put some masking paper down and then next
we will come back with some plastic and cover
the rest of the vehicle, the jeep.
And also notice on the side of the walls there,
the curtains, I have some plastic hung there too
because this bed liner, it will spray pretty far.
If you go up passed that lip when you're spraying
you know it may get the wall a little bit.
So it may be a good idea to put plastic around the sides
of where you're gonna be spraying the bed liner
and so now we're getting the plastic
and we're covering the entire jeep.
And we'll just spread it out and this is just plastic
that we use for covering cars all the time.
I think this is made by PPG.
Three Hill makes it, a bunch of people make the plastic
but it basically spreads out and will cover the entire car
and then once we have it spread out the way we want it,
we can cut this and then take the plastic to the paper
and now we won't have any areas on the entire jeep
that will get over spray.
Another thing I didn't mention.
I don't know if you can see it now
but we had some smaller holes that's hard to mask
and if you have threaded holes or anything like that,
you wanna make sure that you cover those
because you don't want bed liner to get
inside of those threads.
What we do is we use earplugs.
We'll squeeze the earplugs, push them in that hole
and that earplug will expand and that will protect
those threats from getting bed liner on it.
If you get bed liner in there, it's gonna be very difficult
to get your bolts back in.
So we are cutting the plastic now, getting it ready.
Don't get in a hurry on this step.
I know masking is not the funnest task.
Take some time but it is very important
to keep everything from getting over spray on it.
Now step 6, once we have it all masked off,
now we're ready to do our final cleaning.
We're gonna wipe it down one more time.
SEM makes a product called SEM Solve
which works good for this.
It's just a prep-cleaner or any other approved wax
and grease remover will work.
But be sure that you have the surface completely clean,
all contaminants removed, silicon removed.
And this will eliminate a lot of problems.
I know with pain it can cause fish eyes.
I'm not sure with the bed liner but it could cause
adhesion problems.
Just a lot of problems that you can eliminate
real fast just by properly cleaning this surface
and having it ready for the coating.
And just like with any paint job,
I'll mention that you know it's all in the prep.
It is very important and I really recommend
not to skip through or rush through these steps.
And step seven, if you have any bare metal spots
where you sanded through, that's gonna need to be primed
with some epoxy or some direct metal primer surfacer.
And then you need to allow it to dry, the recommended time,
and then sand those spots with 220 to 180 to provide
the adhesion.
Now they do point out in their technical data sheet
not to use self-etch primer.
I think the acid in it will react with the bed liner.
So do not use self-etch primer.
And then once you have your spots primed,
your spots that were metal, you know like I said
just scuff them up and re-clean it, re-clean the surface
wiping it down with the wax or the grease remover
and then you're ready to spray your bed liner.
Now on this jeep was a little bit different
then your bed will be, but we already had it epoxied
so we just went ahead and epoxied the entire thing again
to make sure that all that bare metal was covered,
that sand blasted metal and then we came back
and prepped it and got it ready for the bed liner.
But probably if you're doing a bed, a pickup bed,
you're probly not gonna have to worry about
having so many metal spots.
Just a few spots you're probly gonna sand through.
But unless you have a lot of rust in there,
you'll need to get all that out.
Otherwise, just prime the spots, sand them,
clean it and then you're ready for the bed liner.
Okay, step eight, we are going to shake the catalyst
and the bed liner coating separately.
Directions said to shake them for about two minutes
and then we're gonna mix six and a half ounces
of the catalyst to the quarts.
It comes with four quarts and you're gonna mix six
and a half ounces to one of the quart containers
for your first bottle that you're gonna spray
onto the surface.
Now with got the Rock-it Liner kit
and this comes with everything you need.
It comes with four quarts of the coating,
the catalyst, a quart of catalyst.
It comes with the gun to spray it with
and a measuring cup.
And then all you have to do is screw the tube
onto the gun, that goes down in the bottle
and then put an air regulator on the end of it.
And the gun is ready to go.
And the gun will fit straight into the quart cup
when you go to spray it on.
Now we are shaking the containers, the bedliner,
and the hardener for two minutes like the directions said
just to get it ready and then we'll start mixing
and pouring the products together.
So here's the measuring cup.
You pour six and a half ounces into this cup
and then once you have six and a half ounces poured out,
you will open the lid to the bed liner,
pour in there and then stir it up.
And be certain to always close the lids on these
so that it doesn't get spilled accidentally
while in between containers that you're mixing up,
bed liner coatings.
So we'll keep the lid on.
Now we've got that open and we'll pour the six
and a half ounces of catalyst into the container.
There's enough room in there for the six and a half ounces
of catalyst.
Pour that in there, stir it up, and we are ready
to start spraying this bed coating.
And step nine, before we start spraying,
we need to attach the gun to the quart
and we need to set the pressure.
Now they recommend anywhere from 45 and 60 PSI
and I recommend that you experiment like we are here
because that is gonna determine the texture of the product.
So try 45 and 65 and see what texture you like the best.
And now to the part you've probly been waiting for
and that is applications.
They recommend applying two to three coats, light coats.
They really stress the light coats
and you need to wait 15 minutes between each coat.
Now they really stress not to put this on too thick
to make sure that it is light coats
because if you put this on too thick, too fast
too soon, it's gonna cause you a lot of problems.
So yeah be sure and just put two to three light coats.
Allow each coat to set for 15 minutes,
you know dry 15 minutes before you apply the next coat.
Now the application on this jeep probably is going to be
a little different than a truck bed.
We can get to all this from the outside
without having to get in.
Now in a truck bed, it's probably gonna be better
if you jump in the truck bed and do the sides,
put a coat on the sides.
Put a coat on the sides, allow it to dry it for 15 minutes
and then do another coat on the sides.
And then come back and spray the bottom you know
a separate time.
And that will make it a lot easier to get in and out
of the pickup.
Well if you sprayed to bottom, you wouldn't be able
to get in and out of it until it dried so
that will make it a lot easier for a pickup.
Like I said on this jeep, I mean we was able
to get to all of this from the outside
and as you see, hold back pretty far and this stuff
sprays on and like I said on this first coat
you don't wanna fully cover.
On the instructions it said you know you wanna be able
to see through it just a little bit so that it can breathe
until you get the next coat on.
So I think light coats is key.
I think they may have had some problems with the lifting
or different problems if you're trying to put it on
too thick or maybe it doesn't dry like it should.
It might trap some solvents in there where it can't escape
so you know don't try and put this stuff on too thick.
And I think generally on your truck beds
one kit should do it.
One kit did this one and we have a little bit leftover
and we put two coats on an entire inside of this jeep
and as you'll see here in a little bit,
I mean it looks really really good.
It turned out really good.
But a lot of angles on this jeep, on a truck bed
it's more squared, probly would have this much trouble
but you know he's getting up under the dash
and he's getting the different sides of the shifter.
You know we've got a lot of angles making
it a little bit more harder than a pickup bed would
but it's all worth the effort here.
Now I wanted you to see this full process
of the spray, the spray itself.
I didn't want to edit any of this out.
So I'm just gonna give you a few minutes to watch this video
as he puts this first coat on and after
he gets the first coat applied I will be back.
(country music)
Okay we got the first coat applied and allowed it to dry
and least that 15 minutes flash time that they recommend
and now we're coming back with the 2nd coat.
Now one thing I would like to mention
that I didn't mention during the first coat
is you do want to be in a well-ventilated area
and wear a respirator.
We are in a prep booth which has fans
that help suck out the over spray.
So be sure that you're in a well-ventilated area
when you're spraying this.
Now he's coming back with the second coat.
You wanna basically follow the same process
putting on a light coat, not getting it on too heavy
in any one spot.
And we get this done and we will be done with this bed liner
(electronic music)
Now one final step, step 11, you want to unmask it.
You want to do this immediately after you're done spraying
because if this stuff starts hardening up on you,
it's gonna be very difficult to unmask.
So as soon as you're done with that final coat,
start unmasking and then allow it to dry 48 hours.
Now I will put some links down in the description
with a PDF where you can print the steps that we took.
I also have that short version video.
Have some information about these different products
that we use.
Be sure and click down in the description area
to learn more information.
So there you have it.
If you're wanting to spray inside of a jeep or a bed liner,
there's the steps we took and soon
I'll be coming up with another video
where I'm spraying inside the boat with an SEM product
called Marine Coating.
