Paint and West System Epoxy
I painted our deck two, soon to be three seasons ago. You do NOT want to have to do it again anytime soon, but if you''vre removed the hardware and taken it down to the epoxy, the hardest part is over. After testing with one-part polyurethane, (poor results-did not stand up to any usage), I used two part polyurethane from Interlux. Their product can go on with a roller (use a 6" solvent resistant roller, available in bags of 6 from Home Depot) and they have an 800 number helpline that is very patient and good at hand-holding. If I were to do it again, I would do a better job taping off and covering all the hardware (on a 36'' boat, we didn''t want to have to re-bed everything) and I would suggest going with the maximum reccommended nonskid granules in each topcoat. (I used only half the max in the first topcoat, then the max, and the footing is ok, but not as nonskid as it could be.) The paint is holding up well, and I expect at least another five years before we have to even think about it again.
