Sherwin Williams automotive division makes a two part Urethane finish called Sunfire.It's the equivilent of Imron,and other two part urethane finishes.
I've sprayed a couple aluminum boats with it and is an awesome finish.I have it on a 18' starcraft aluminum that i use on local lakes,and some brackish water.It has held up unbelievably well.I've kept it in a slip for two weeks with no pitting or blistering.This finish is now 12 years old,with tons of use,and still looks new.
Okay,i know this is an aluminum boat,but please go easy on me,i'm only posting it for the picture of the paint.
The pics.not the best,and doesn't show the finish as good as it really is,but it will give you some idea how it looks.I'm thinking of using it on my Tsunami restoration.
