I'm about to paint my aluminum bass tracker to be a duck boat but didnt know which primer to use... any thoughts..
What does etching primer do different from clean metal primer? Thanks

Re: regular primer or etching primer?

Most primers are designed for use with wood or steel. Aluminum and galvanized metal require a primer that will bond to the substrate and not peel.

So, to answer your question you MUST use a self-etching primer. NAPA auto stores have the best and most cost effective product.

Now, if your boat is already painted, no need for primer. Just prime any bare metal spots.

Just to clarify, when I said MUST, no you can use anything else if you don't care how well it sticks....LOL.

Bare aluminum? or already painted boat?

All bare spots and bare aluminum should be treated with alodine, primed with zinc chromate then painted..... only if you want to do it properly and have the paint stick.

I was paying $19 a can from a marine store. Then I found an auto paint shop for $12. NAPA charges just short of $7. How much is Advance?
