I sent you a pm on the gelcoat.
I wouldn't use gel coat,It's way to labor intensive to get a perfect finish.
I'd definitely go with paint,and I wouldn't go with the EasyPoxy.The EasyPoxy is a single part urethane,and although it's a real nice durable paint with a very nice finish,It can't come close to the two part urethanes like Awlgrip,Signature,Perfection, etc in the durability,gloss or longevity factors.
The perfection(Interlux) works great with the roll and tip method and many guys say the same about the Sterling.I used a two part urethane made by Epifanes on my 23 and although I sprayed it,it also works good with roll and tip application.
These two part finishes are incredibly durable and highly fade resistant.They are the way to go.
