Hey folks..... sorry if this is a stupid question but when A boat like a RT has its hull painted do/can you still apply anti-fouling paint? We have always had white gel coat sailboats so we have always apply bottom paint since the boat was in the water for 5 months. Thx in advance!

If I understand your question, if your boat is in water that can foul it then yes you can and probably should put bottom paint on any colour gel coat. Here on the west coast, growth occurs on fiberglass hulls and on metal hulls, on ropes, on chains, on everything... I see guys that have there boats up on the beach scraping the hulls and complaining about how much work it is. Seems like that’s a lot more work than putting primer and bottom paint on, but each to their own.

I think I have cornered the market on dumb questions on this site.
But yes, there is no problem with putting bottom paint on your paint-over-gel-coat bottom. Your boatyard will prep the surface by sanding it to make it smooth. There will already be a primer coat on, but that may need to be repainted.
I just got through putting Micron 66 on my tug and they (the boatyard) sanded down to the primer coat before putting two fat coats on. I live in a marina (Pier 39 in San Francisco) where the sea lion poo and other foulness leads to epic bottom growth during the spring and summer. My relatively new tug had Washington bottom paint on it that RT put on. It cannot hold up under the epic onslaught of encrustation that is Fisherman's Wharf and vicinity. Although I think the Florida tugs have it worse.
Good luck! Have no fear about slapping some paint on it and for sure, ask around to find what locals use.

I believe another benefit to bottom paint, on a boat left in the water, is prevention of osmosis, which can result in blistering of the fiberglass.
