Can Aluminum be painted?

Interestingly, I once bought a jon boat that had terribly blistered paint. I scraped all the bubbles, and sanded the spots clean.

Then I rolled on a coat of Home Depot's Behr deck paint with a hotdog roller.

Amazingly, I just sold the boat 5 years later, and the paint still looked just like it had just been done!

This boat was used in salt water, but I DID rinse it after every use. I think in an all-salt environment, it would have corroded, but it worke GREAT.

This is NOT for professional-level work, but might help some guy who just wants to paint his jon.
