Back in the '70s USN had us using Zinc Chromate Yellow to prime all our aluminum superstructure and gear. Also in automotive paints they use an epoxy primer. However the only real reason to paint aluminum is to give it color. Aluminum develops a coating of self-produced aluminum oxide that coats and protects it from corrosion. Good discussion here of the chemistry; https://www.boatdesign.net/threads/can-aluminum-be-painted.31754/

It takes some sort of self etching primer to stick. There are numerous brands out there. good point- I remember using white vinegar to etch galvanized gutters back in the day

I used white vinegar and a scotch brite pad on mine. Then I spray painted it with Krylon camo paint. Has held up well.
It is what it is.

Prepping the aluminum to start with Is Important. Like others said you need to use some type of acid to etch the metal before painting. If I remember I used a concert cleaner It's a mild acid to etch my boat before painting.

I have a 10' jon boat strictly for trapping. Guy before me painted it yellow and peeling bad. Going to pressure wash it to get the rest off. Is there a paint that sticks to aluminum boats ? Olive green/marsh brown would be nice. That way I could ditch it at nite without having to load back into the truck. I just used some top shelf on my old Jon boat. It's a combination of several colors left over from painting cars. It's been on there for 20 years but it's really faded out now. Just sand it good any paint will stick to it.
