- Hey, Donnie Smith here with Collisionblast.com.
In this video, we've got a fender that's damaged.
The door had opened up into this fender
and caused the edge to be damaged,
and also on the top surface,
it caused that to push up and be high.
So we're gonna show you how to sharpen that edge up
and push that high down.
So I've already got the fender off the car,
and I was gonna get another fender
but we couldn't find one, so we're just gonna
be repairing this one.
Now, I'm gettin' a body hammer, and a dolly,
this is a wedge dolly, or comma dolly,
and it works good for edges 'cause it has that edge
that can get behind that, and that's what we're
really tryin' to concentrate on, is sharpen that edge,
just to push that edge out, and as we tap and hammer
on this high area and kinda roll that damage out,
and so you can see I'm hammering here.
Now what I wanna try to do most of the time
whenever I'm roughin' this out, I want it hammer off dolly,
where I'm not actually hammering on the dolly,
and you can hear a difference, whenever you hammer on dolly
you're gonna hear that ping, and I wanna try to eliminate
that at this point, and later on during the repair process
I'll be doin' some hammer on dolly, and we'll show you that.
Right now I'm just trying to roll that high out,
and kinda push it into the edge.
I got another tool here that wasn't workin' as well
as I thought it would, so I'm gonna see if I can get this
behind there to help sharpen that edge
as I roll this high out.
(energetic electric guitar music)
(metal banging)
So I'm just continuin' this process,
working from one end to the other as I roll that damage out,
and you wanna check your progress often.
I'll do some hammerin' and dolly work,
there's also a little bit of damage there on the bottom.
Now I wanna do a little bit of work
and kinda monitor my work,
make sure it's doin' the right thing.
(metal banging)
Now I'm goin' up to the upper part of the damage there.
(energetic electric guitar music)
(metal banging)
And also notice I'm not just hammering as hard as I can,
you wanna do a series of smaller strikes
rather than tryin' to do it all in one or two strikes.
May take a little bit longer, but the finished products
will come out a lot better, 'cause if you just try
to hammer it like you're tryin' to frame a house
or something, you're gonna end up damaging the metal
more than you repair it, so try to get in the habit
of doin' a series of smaller hammer strikes.
(upbeat electric guitar music)
Okay, now what I have is a slapping file,
and this is gonna be a hammer on dolly technique.
I've got the majority of the dent repaired,
and now I'm usin' the slapping file to slap straight down
on the dolly that's behind that, and that just helps
smooth out any ripples, it's for the final straightening.
You don't wanna hammer on dolly too much,
'cause if you do, that's gonna stretch the metal,
and then we're gonna have to shrink it
so just in the final stages we're gonna use this method.
(upbeat electric guitar music)
And now I am locating just the few highs that I have,
just to knock them down with a pick,
this is my final detail work, just to try to level
any small highs that I have,
and as I monitor this, there might be some lows in there,
I can get to the backside with the hammer,
and knock those out the other way, so just kinda tryin'
to level it the best I can.
Now I'm on the backside, there's a small low,
and I'm gonna try to tap out, and also when usin'
the pick side of this hammer, again, don't strike too hard
or you're gonna damage the fender, or whatever panel
that you're working on.
(upbeat electric guitar music)
Now what I have is a sanding block.
As I mentioned with these thinner metals,
you don't really wanna get a body file like we used to.
Now I'm doing this to help locate the lows and highs
and make sure that it is straight,
and what this'll do is it'll sand the paint surface,
but if there's any lows, that the paint's gonna stay
in that area, and that'll help me identify
that this is still a low area,
or if a area sands to metal extremely fast,
that'll help let me know that
that area is high, so if you see any
really shiny metal areas, or any areas
that have paint in 'em, you know some additional attention
may be needed to straighten the panel.
(energetic electric guitar music)
It may take just a little bit longer sanding,
and I'm doin' this, you can use 36 or 80,
hit it with a body file, but you're not shaving metal off,
and that's somethin' we don't wanna do
with these thinner metals.
By using the sanding block method, it did help me locate
some areas that I need to do some additional straightening,
so at this time I'm gonna do the additional straightening
that it needs, now this is just minor imperfections,
and we wanna get this close to what it should be,
most body fillers recommend, I like to get it within
1/8 of an inch, where you don't have to use more
than 1/8 inch of body filler.
Most manufacturers say 1/4,
but I am gettin' this finished out to where
really this is not gonna take much body filler at all.
It is pretty straight, and with these thinner metals,
you wanna get it really good, but you don't wanna try
to get it perfect, 'cause if you try to work
this thin metal too much, it's gonna become work hardened,
become brittle, it could even break on ya, so
block sand it again just to make sure that it's
worked out well, or good enough to where I'm happy with it
to put some body filler on it, and again,
you wanna check your progress often,
and do that by usin' the flat of your hand,
and again, I blocked it out, felt of it, and I found
a little bit more damage, and so I'm gonna work that out.
And by doing this, you're going to get the metal straighter,
and it's gonna take a lot less time
whenever you get to the body filler stages.
(metal banging)
But like I mentioned, don't try to overwork metal,
with these thin metals, 'cause that can cause you
more problems as well.
So I'm hammerin' a dolly.
Hammerin' dolly, I'm hammerin' only,
I'm hammerin' on dolly here, and this is just
for the final straightening, and again, you don't wanna
do that much or you're gonna stretch the metal.
(lively electric guitar music)
Okay, now when I think that it feels good,
I'm gonna block it out one more time, see where I'm at,
and then once I have this blocked out,
and I'm happy with it, there's one last step that I wanna do
before I start applying body filler.
Now that it feels good, I am gonna get the fender,
I'm gonna take it off, and I'm gonna put it on the car.
I'm gonna test-fit it to make sure all the curves
and contours lines up with the door, 'cause the last thing
we wanna do is get that thing, put body filler on it,
put it on the car and realize that it doesn't fit properly.
So I'm gonna put it on the car, I'm gonna line it up,
and I'm gonna have to take this tape off
where I can see real good, make sure that it is
lining up with the door the way it should.
So I'll go ahead and align it, and see if it fits up.
(upbeat electric guitar music)
And it's a good thing I did that,
because the damage looks straight, you would not have known,
but I put it on the car, and realized the fender needs
just a little bit more overall curve to it.
So I'm just gonna use my hands to bend it
and give it that curve.
Now I wanna test-fit it one more time, make sure it fits,
and it did this time, and in the next video,
I'm gonna show you how to apply the body filler.
