Painting aluminum boats?

[Hack_Fisherman]

Any of you guys paint aluminum boat before? 
 

before I put the floors in my old Starcraft, I’m thinking I should repaint the bottom while I have the chance. 
 

I don't want to strip off the old paint though. Can anyone recommend a good roll on paint and primer? There may be some exposed aluminum after sanding

Just use zinc chromate primer on any bare aluminum followed with a decent marine topside paint.  For price Rustoleum Topside works pretty good.

I did this $250.00 jon boat for my nephews to putz around in with Rustoleum and I used truck bed liner for the interior.

Thanks. I read that Rusoleum Topside had good reviews for aptly named topside, but I’m doing the bottom. 
 

how has the paint stood up in your application?

 

looks good!

The bottom is painted already? Just prep it well, and clean it really good before paint. Wipe it all really good with acetone and a clean rag. The Prep is really the key. Interlux makes a good quality paint that's readily available in Canada. I painted my whole boat with exterior latex and it is holding up really well. I needed ultra flat paint though, so it was a little harder to find an actual marine grade paint that was ultra flat and available in canada. 

Get a good self etching primer to hit the bare metal, or it will just peel off.
