Okay Jim here is the scoop as I see it with Durabak. Like everything else results are 100% base on how you prep. Do not look for Durabak to hide blemishes, cracks or other imperfections. I prefer durabak on the decks only. I am not sure if I would like it on the house. It might give you a to heavy of an appearance. Cleaning the durabak once applied can be done with a stiff deck brush and biodegradable soap. Rolling on Durabak I think is preferable over spraying. One coat of the anti skid is enough on the decks. Followed by several coats of smooth until you are happy. I was happy at three coats of the smooth.
These pictures look gray but they are really a bright white. No discoloration has taken place after a month.
Clean edges were accomplished with masking off and then trimming with a razor blade. Slow work but worth the results.
The middle deck is a one piece cap. No seams and a more finished look.
The fly-bridge deck has seems and it was impossible to sand them flush without sanding thru the fiberglass.
I am confidant that Durabak will provide many years of trouble free decking and I would not hesitate to do it again.
