barrier coat as finish?

[Davoarts]

I have a 73 catalina 22 that has been on a trailer for two years and I bought it with the intention of fixing it up to race/weekend cruise. It will not stay in the water more than a few days at a time and I know that I technically don't even need to worry about painting it except that I want to anyways just for cosmetic purposes and a change of color. It has been painted before and most of the old paint has worn off down to the gelcoat from what I can tell, so I intend to sand down to the gelcoat and properly prep and I picked up the Interlux 2000E thinking that since it has been dry for two years now would be the best time to apply the barrier coat.

My question is, can I just apply the barrier coat and leave it at that without any bottom paint since I will be trailering it and cleaning it off after every sail? Do I NEED to put a bottom paint on?

If it only stays in the water a few days at a time, I don't think you need bottom paint (or barrier coat for that matter).

I would check with Interlux. Barrier coat usually doesn't have to deal with uv but yours will. As it is an epoxy it may degrade quickly from sun exposure.
