Dent Repair: How To Repair A Dent Using A Body Hammer and Stud Welder Gun

(acoustic guitar strumming) – Hey, this is Donnie Smith, and welcome to another Eastwood video. This video series, we’re showing you how to paint a Mustang
from start to finish. In this video, we’re gonna
show you how to repair a dent, and we’re using some Eastwood
hammers and a stud welder gun. Be sure and visit our friends at Eastwood by clicking right here. Okay, so let’s get started. Okay, what the students are doing here is they’re block sanding the paint, and we’re using long blocks,
and as we block sand that, that’s gonna help us identify the lows, anywhere there’s a dent or
low area is gonna stay glossy. And then, we’ll mark them,
so we can repair the dents. Okay now, we have this dent here. Now, it’s a fair-sized dent, but the thing about it is
you can’t get to the backside because it’s double walled here, so we’re gonna have to
pull from this side, and to do that, we’re gonna
use a stud welder gun. And in order to do that, it’s
gonna have to be bare metal, but before we start taking the
metal off or the paint off, we wanna kind of see what’s going on. We know this body line’s
pushed in right here. You can see that, and
it’s also pushed in here, and obviously, there’s a low here, but what’s equally important
is note this high area. There’s like an eyebrow right here, so it’s really high, and you
can feel it with your hand. And you can feel it, so as
we’re moving this body line out and this low out, we need to be sure, and knock this high area
down at the same time. If you try to just pull
out on the low area and the body line, this
high is gonna stay here. First, before we start using this method, we’re gonna have to take it down to paint. We’re gonna use an 80 grit DA, and we’re gonna take this
down about four inches passed the repair area, so that we have plenty of metal to work with. And also, you do not wanna
get body filler on your paint, so that’s one reason
that we’re gonna do that. Now, we have another low
here, and we’re gonna go ahead and fix that one. That’s pretty low. Probably one nail will fix that, so we’ll go ahead, and take
this down to metal as well. (sanding) (acoustic guitar strumming) Now, you want to remove
as much of the paint as you can with the DA that
way you do not remove metal, but there’s gonna be some of
the area in your direct damage that may be harder to get out, so we’re gonna use a grinder with a three inch Roloc disc on it with 50 grit. Okay now, we’ve got this to bare steel. Now, what I’m gonna do
is put some of these stud nails on there, and basically, it’s just a stud, and that’s
why it has to be bare metal because it’s actually gonna be welded, tacked to the surface. Okay now, I’ve got three
nails on this body line. This is the low area of this body line, and I’ve got the high up here, and I intend to pull on
these. Now when I’m pulling, I like to use these T handles. I’m not a big fan. I’ve
mentioned in other videos. I’m not a fan of the slide hammers because usually if you’re using that, you’re pulling in one direction. If I use a sliding hammer,
I might use it just to pull, so I can tap down, but
not use that slide action because that’s just
gonna stretch the metal rather than roll it back
where it needs to go. So I’m gonna use this T handle, and as I’m using the T
handle, and I’m pulling on it, I want to put quite a bit of force, but remember when you’re
pulling on something, never pull too hard like you’re pulling tug-of-war because if it comes loose, you don’t wanna go flying backwards. So I’m just gonna put some force on it, and then I’m gonna tap down
on this high right here. And another thing is, wanna kind of work from the outside in. So I’m gonna pull on these two, and then I’m gonna pull
on the center stud. (hammering) (sanding) Well that wraps it up for this video. We don’t wanna make these videos too long, so 10, 15 minutes max, but in the next video,
we’re gonna show you how to apply body filler. We really appreciate you
watching each one of our videos. Thanks for watching, and be
sure and give us a thumbs up, and give us a like. Visit
our friends at Eastwood, and check out some of our other
videos. We’d appreciate it. We’ll see you next
week’s video. Take care. (acoustic guitar strumming)

  1. Donnie love your videos. I'm an airbrush artist and I'm getting ready to start working on my Grand Prix which I want to do a complete color change and some graphics I know your videos will come handy to make sure I take care of the very little details that will make a big difference between a good and a great paint job. 


  3. Thanks for this video. Do you use extension cord? if you do, what is length and gauge wire did you use? i know this tool requires 20 amp, and lots of 10 gauge extension cords only support 15 amp. It is hard to find a right extension cord for this tool.

  4. never knew what those little studs sticking out of body panels were for until now. one of the neatest things I've seen. thanks D

  5. It's me again unless you have the real expensive stud machine. Drill holes then fiberglass bondo then bondo it as usual this stuff takes to long and you have better control with the metal using pull hooks and hammering down the crown.
