I have used Sig Finish with great success - I still have people come up to the boat and cannot believe that it was a rolled on application -
I did the deck, topsides and top of bracket with Sig Finish and Intergrip non-skid additive - they came out great as well. I applied as per Sig. Finish instructions mixing the grit and rolling on pretty heavy.
This is some tough paint.. even after several anchor knocks and lots of abuse I have yet to have any problems.
I believe that someone over on the ClassicMako site did Sig. Finish in a dark blue color and they were not happy with the results - not sure how they applied the paint or what happened but I'm sure a dark blue will show more imperfections than other colors..
Good Luck..
