Just so we don't confuse the OP, don't use Stainless wire on the aluminum front fenders.. stainless and aluminum typically will only weld together with HIGH explosives.. ever seen Explosion Welding.. COOL STUFF!

Had it done at a local weld shop. I pushed the edge of the hole IN so that when it was welded I could grind down without grinding the weld plug loose...You just about cant tell where the holes were even before primer.

This is very useful information:

Independent of whether it is aluminium or steel; welding of thin metal is not for beginners. As others have pointed out, the methods need to be know, proper equipment is needed and quite a lot of practice is also needed on scrap metal pieces.

It is possible to solder aluminium. I always see it at car shows and untill recently, I didn't believe in it. I bought a DIY kit however and last weekend I tried it out. The aluminium part was so big, I had to heat it on the kitchen stove, helped by a propane burner. And still, I didn't succeed.
You can see however that it works: http://www.youtube.com/watch?v=OLvDHwQFvAM
And read some more info here: http://www.aws.org/wj/2004/02/046/
After a lot of questioning to the seller at the market, he let go of the biggest secret: The wire you buy probably is just a little aluminium, and a lot of zinc which has a lower melting point than aluminium.

My favorite welding trick is to back the hole with a copper plate on thin gauge metal. The alu won't stick to the copper, and the copper eats the heat and keeps the panel from warping. As I've said before, the copper also prevents hole-blowing. Best trick I ever learned. Bronze works as well if you can't get copper.

Copper,brass,bronze for backing aluminum.And you can use aluminum as a backer when welding steel and stainless steel.Aluminum sucks the heat right out of the parts and prevents warping. Ed
