Probably already covered in a thread somewhere,  but any suggestions on good external paint for an aluminum boat that aint rustoleum?  ive already done the prep work, just looking for some thoughts on a good brand, money not an issue.   I looked into those specialty paints they make for airboats, problem with those is they are too slick for my boat, as i don't want it falling off my trailer (which will happen with some of those) .  

I am a retired Air Craft Mech. and all aluminum planes were finished with Polyurethane.

Darn rear bullet proof finish.
