What's up Youtube today we're going to show you how we fix some major rust problems on the vintage
van we're going to show you the good the bad and the ugly actually there is no good it's just
really bad and ugly this is my nightmare just a quick disclaimer this is my first time doing
this type of repair I've never done it before I don't have a welder I don't know how to weld I'm
going to be doing it the alternative way which is actually the cheapest way because I'm just trying
to get this done without spending a bunch of money so I'm going to show you how to do that if this
video does help you make sure to hit the like button and if you're a body guy and this video
makes you gag and horrifies you make sure to hit the dislike button twice and let's get right into
it because I got a lot of shit to do real quick this is what I'm going to use to do the repair and
I'll have them all linked below so you can check it out because this is definitely the cheapest way
that I could figure out how to do these repairs we got a chemical treatment some safety gear and it's
basically going to be repaired with fiberglass using uh this mesh right here and we got sandpaper
and some grinding wheels and a mixing board and some other stuff so I'm gonna get right into it
and show you how I do the repair using this stuff right here so let me go ahead and show you how
bad the rust actually is over here yeah check that out guys we have some major rest issues
there's a bunch here on the driver's floorboard and also here on the floor in the back then we
pulled out the windshield and found even more it looks like this seems to be the worst of the
rust right here in this bottom corner for now I'm just going to clean up all this leftover
glue and the surface rust around the rest of it and then i'll get back to this in a minute
All right so we've grinded out all the rust and let me show you what we're working with here
this is pretty much the gnarliest gaping rust hole on the whole van so it's a pretty serious problem
this is probably as bad as it gets before you actually need to remove the whole piece
because this method works for smaller rust holes and this is probably as big as you want to get it
with this type of repair so now we're going to go ahead and fill the hole and patch it and repair it
so let's get into that first we're going to use this metal prep which is basically
just phosphoric acid it chemically reacts with the rust converting it to a zinc phosphate
which can then be sanded and painted here's what the metal looks like after it's been treated
as you can see it kind of has a salty like residue where over here that's not treated
it's just bare shiny metal now I'm just going to grind the rest one more good
Time then hammer it down to make some room for the fiberglass
Then we gotta scuff it really good with some
40 grit sandpaper and then a quick clean with some degreaser
Now I'm cutting the mesh backing to the right size and setting it in place
to strengthen and hold the fiberglass
Trimming off any excess
and here it is ready to get a solid layer of fiberglass filler
just gotta mix it up real quick
This is a short strand fiberglass reinforced filler that's about four to five times stronger
than just regular filler yeah this stuff's also called kitty hair and I guess that's
because the fiberglass but you can see why it's pretty much meant to fill rust holes like this
Now I'm applying the filler pushing it in firmly but not too hard
and also kind of molding it into place
Then I'm using 40 grit sandpaper to do the actual shaping
Now that I got it looking about right I can
see there's a few other spots that are going to need some more filler
a couple low spots here and there so I'm gonna mix up another batch and apply a second coat
so
Just uh smoothing it out a little bit before it starts to kick and harden up too much
and here's the second coat just gonna let it harden up and dry
and now it's time to sand it again and shape it
and this is how it looks came out perfect
and now here's with two coats of primer
All right moving on to the inside we got this big hole in the floor so for now i'm
gonna grind it with the wire wheel like before we're gonna prep it with some metal
prep it's basically just phosphoric acid and I put it in a spray bottle
so after it's grinded I'll spray it down then tomorrow we're gonna let Lidia the fiberglass
master go ahead and patch it up and take care of it normally you would probably cut out the
floor pan and weld it but we're cheap and we're trying to get it done so I'm gonna
use the old surfboard ding repair kit that I have it's just like some fiberglass and resin
and uh yeah we'll show you how that works out so stay tuned time to start grinding
All right
So that's that we got it grinded down got all the rust knocked off
now we're gonna soak it with some metal prep and let it sit overnight
So we got the metal prep on there I'm just gonna rub it in with this brush
and then we're gonna let it sit overnight and then come back tomorrow and we're gonna sand it and
then we'll start fixing it up so what this stuff is gonna do is it's gonna treat the metal and
cause a chemical reaction to turn the rust into I think like zinc phosphate or something like that
we'll be able to seal it up so it stops the rust completely this is gonna be under the floor so
we're not too big on how it's gonna look so we're just gonna do a little sloppy job just to seal it
and stop more rust from happening and then we'll be good because we're gonna put a floor over it
anyway so we'll let it sit overnight and get back to it tomorrow before we move forward last night
i had to spray the bottom side of this with the rust reformer because it's a really hard place to
reach and if you don't stop the rest from the back side it's eventually just going to rest through
so we use this to kind of spray the places that are on the back side and then we're going to show
you how we fix the top side here right now now we're going to do all the sanding right
here in this area before we start doing the fiberglass work it should be pretty easy guys
Now I'm sending by hand all the little holes and little areas that you cannot reach with the
sander you know just use the little corner right there and just keep sanding until
you know everything looks kind of clean you know so yeah
now we're gonna put the mesh to add some extra support
Okay it's going in slowly I just need to here we go slowly okay okay
beast
Now we're going to use Philip ding repair to patch this hole guys
Yeah this is my surfboard ding repair kit which is you know it's fiberglass so it'll work
yeah guys we're gonna mix it up I have the brush right here and we're just gonna mix
it up in this cup really quick and then we're going to apply it with this brush
apply the harder there are you ready all right the fiberglass master
well I have some experience with fiberglass like I did in the RV you know in the van
all right so we're gonna dub this I'm gonna put a little bit on this first
Sticks a little bit in it get a little wet we're gonna put this one
and now we're gonna apply this
Yeah when you put fiberglass you want to just do tap you want to just tap
it in you know tap tapped up just like that you know you it's not like paint
you know you just have to tap it tap it top it just like that so it soaks in real good
and now we're just gonna slap this other one in
That's so dark we're putting another layer down guys
Okay right now we're gonna let it dry we put like three layers but we need to let it dry to see how
it goes and then maybe we put another layer later but yeah I think it's looking really good guys
Alright so here's the front area I have the Bondo fiberglass over the surfboard
ding repair fiberglass it's hard as a rock it's sealed and now we're going to put on
por-15 it literally says paint directly over rust it's a rust preventative
and it's a nice black color so we're gonna do the whole floor
um up until this point here with por-15 and Lidia's gonna paint that on so let's get to Lidia
I just applied the second coat and now we're gonna wait overnight and see how it
looks tomorrow hopefully it looks good and it looks better than it was so that's good
all right see you tomorrow all right good morning the por 15 is all dried up and it's
good to go it looks pretty good oh yeah it looks so much better guys i'm glad we did this job
we're able to fix it with my ding repair kit as cheap as possible it didn't take too long and it
looks pretty good and hopefully we shouldn't have to worry about any more rust for a really long
