Got a good RF fender (1972), for a small bumper, but it has holes for trim. I will need to fill them, I guess weld? Seems like a lot of work to get it nice, any good info, and pics how to do it? I have a wire welder, but never did anything like this, well that had to show anyhow! But I would be interested in trading for one without holes!!!
Get yourself, a piece of copper pipe, pound it flat. Clean up the holes real good, hold the copper behind the hole, and mig weld them up. Easy, and it's the best way to fill the holes. Just take it slow, so you don't warp any spots.
How would someone fill in the trim holes on a door? The ones that have the inner brace? (Sorry for the thread jack)
I wouldn't use it for trim holes. That is how my trim holes were "first" fixed. After paint.....they showed through. Had them welded up, and had the car repainted. Welding is the only way to fix it IMO.
I used solder and tin patches on a LeMans I used to have. I read about it in a magazine so I tried it. I didn't have a welder at the time so it seemed like a reasonable solution. Last time I saw the car it was still holding up very well.
Welding is the answer, all you have to do is a bunch of little spot welds to fill them up so you don't warp the metal. Then grind them flat and skim coat them with filler.
Epoxy will work if you don't try it on a hot day because it will dry too fast and you will never feather out the patch. You will need to concave the hole. A friend done his 1966 Ford Fairlane and it came out great.
You might try what I did. It was pretty easy and worked well http://www.maverick.to/mmb/showthread.php?t=48349&highlight=filling+holes
