My 2 cents:
I refinished the dagger and rudder on my F31 a couple years ago and used interlux perfection which is a 2 part polyurethane paint. Not too hard to get a good finish (I rolled and tipped) but the real problem is dings. You can't simply "re-touch" with this paint. I think Jake alluded to this in one of his responses. I found a work around- fill with filler, sand gently then feather the area with gloss enamel spray paint. This is on the rudder which doesn't stay in the water full time. Yes, not very elegant and seems stupid after all the effort of the perfection, but it works and beats the hell out of dealing with those toxic fumes again. If I have to redo the rudder again, I really might just use the enamel spray paint!!!
