Hull corrosion, Lifetimer. Advice sought.

[Laxputs]

Hi all. Would love your input on this please.

Details:
-Aluminum Lifetimer boat
-20 years + old
-Some minor pitting on hull in about 30 spots at a max depth of 1/3 of the hull. So corrosion eating into the hull. The pitting may have taken place before I owned it and it was hidden by the bottom paint.
-It was bottom painted for most of its life before I owned it. I'd rather not bottom paint anymore and have let it go.
-Only kept in ocean 4 months of year. Zincs. Pressure washed a couple times a year. I dive it regularly too.

Is there a product I can scrape into the pitting? Is there a JB Weld or aluminum filler out there? Any thoughts to fix the hull? Thanks.

Wire brush the pits & use JB weld for now, but you are on borrowed time. The pits will continue to get deeper & will eventually penetrate the hull. I don't think you can stop it in salt water.

Okay thanks. What if I bottom paint? I'm betting the corrosion was from years ago before I bought, but I'm not positive.

Don't use a copper based bottom paint.
