that cold weld aluma rod works better for that
I need more info on what you got. If it's a bateau, and the holes are in the bottom and the aluminum is thin, your better using cold weld or something similar, as I'll proably just make your holes bigger. Now if it's a thicker boat like a skiff with 1/8 or 3/16 I can do that easily. I also have some industrial coating to fix those holes in a bateau.
Yeah I'd say it's pretty thin. Probably 16 gauge? Thanks for your opinion on the matter. I'll use that cold weld stick this afternoon and see how it turns out. I'd imagine that stuff is prone to corrosion if it's not treated correct?
Holes or cracks in the bottom of bateaus are usually there because the metal has worn thin or worn away so they are always hard to weld. I can't tig aluminum some one who can tig aluminum might can fix it. If it were me I would coat the holes. aluminum gets dirty and if it's not clean even weld won't stick. The trick is to make sure it's CLEAN.
