TOPIC: Bottom paint for trailered tinny

What would you use to paint the bottom of a boat that gets trailered to the lake every use? I don't think I need a high tech anti fouling paint. Boat will only see freshwater use.the boat has some type of grey paint at the water line but I'd like to go colored up to my splash rails then polish the top.

A lot of us are using Rustoleum (or another "implement enamel") with hardener. You can do a forum Search on Rustoleum and bring up MANY posts on how to mix, how to apply, etc..
