...Question to add to thread:
Is it feasible to repair aluminum? For example, aluminum pontoons with a puncture or an aluminum jon boat?
Yes, if it's a seam or weld split, or a puncture. Corrosion repair would probably require a thin aluminum plate, and would be dependent on the location. Or, you can just turn a cheap aluminum jon boat into a big planter box like I did. My old jon boat didn't play nice with Cutrine.
Down here, most high end horse trailers are aluminum, and they can require repairs. Check fab shops for experienced tig guys that do that, and you should be good to go.
