Some of the guys on here have painted their 23' boats with the Signature paint with very good results, I used it on my transom when I replaced the rotten wood and am very pleased with it. I'm thinking one of those guys will chime in. You can call Tom at Signature and he can tell you. The number I have from 2009 is, 772-287-6077.

There are others out there that offer the two part epoxy paints, just Google.
