Need some direction on patching some small holes in my trunk. 2 are from rust (maybe 3inches by 1 inch) the others look like they were drilled. I will be putting carpet over it once it is fixed. So far I just sanded the rust down and primered it. Shoul I use bondo or sheet metal. Or should I get a buddy to tack weld somthing in there.

If you have some metal the same thickness i would get him to tack it in, make sure its all clean around the holes and solid. If its the least soft he'll blow right through it with the welder. If youve already stripped it i would weld in the spot work them down and splatter the trunk. I would definitely treat the areas around the holes with a rust inhibitor prior and post weld.

For the drilled holes, you can crawl under the car and hold a heavy chunk of copper over the hole while your buddy welds them up. I had 3-4 rust pinholes in my trunk floor, and I dug them out with an awl to make sure the area was still solid, and filled them that way.

For the big ones, cut back to solid metal and cut patches to fit. If the rust is in the grooves, you can probably get a donor piece here from someone who has to replace the whole trunk floor. Or you could fabricate a duplicate from new steel. I'd butt weld and grind smooth from the top, and probably the bottom, although the fuel tank will probably hide the underside.

Any alternatives that dont involve welding? Some one will probably shoot me if I mention JB weld.

I think if he knows how to weld, you should let JB weld them.

I think JB should weld them too, I have confidence in him. Hey where do you find a chunk of copper anyway? I could really use one. But people around here will steal the copper from your AC if your not careful!:noway:

Try a metal recycler, or a machine shop. You should be able to find a piece that will work. You need something with some mass....maybe 2-3#

ive seen people flatten a copper piece of pipe and hold it with channel locks or something like that..

I will try some of those ideas about the copper.

Dont let welding intimidate you. You will be doing spot welds, not trying to lay down a fantastic bead. Please read up on welding panels before trying though so you dont create more work than neccessary.
