the only problem with painting is that if you knock off a decent job, you'll see every little imperfection. i had 2 coats of primer, and it felt babys butt smooth and looked really good, but after painting the print thru still shows up. you can even see where the old decals were on the bow (name). you can see the hard spots in the hull where the chainplates are, and you can see every dimple 2" below the hull deck joint where the hull is riveted to the deck. that goes part in parcel with a dark glossy finish.... as for the decks, i sprayed 2 coats of primer over the whole thing, and then sprayed perfection off white, mixed 50 50 with flattering agent for all of the "smooth" parts. i'm now rolling on light grey with the intergrip grit mixed in for all the non skid. it's working quite well, pretty uniform distribution of sand but you can see the odd roller mark.... i'll tell you in 2 years if it was tough enough.......
perfection is a pretty easy paint to work with. you'll hear people call it imperfection, but i personally think that most of the work is in the prep. i'm not the smarted cat out there, but I can read the directions and follow them and it turned out ok... you can screw up a job with sterling paint if you halfass the prep...... i've never painted anything bigger than a snowblower in my life, and i got a relatively decent spray job down. it's better than any other homemade paint job i've seen, and i don't have $8 000 into it. theres 3 or 4 decetn sags, and I dont think i'm going to touch them at all.
if you get checking on the internet, theres all kinds of different paint you can use - awlgrip, awlcraft, imron, jet-glo, perfection, etc etce etc. the main thing being that they're 2 part polyurethanes. theres 2 kinds, acrylic and polyester based but i'll leave that fact finding mission up to you.
