We are hauling the boat out on Thursday to do our first Bottom Job since the boat was new. We bought 1 gal & 1 qt of Pettit Trinidad SR. It's a hard epoxy, dual biocide paint. The guys at West Marine said it is the best paint for SW Florida, and will last at least 3 years. Does anyone know if we can put a Hard Antifouling paint, after sanding, over the ablative stuff the factory puts on? We don't have to remove all the paint do we? Do we have to put a primer on first? I got an email question about doing our own bottom job answered about 2 months ago by Don Casey, who encouraged us to do the painting ourselves but he did not give any advice on the best paint to use. He said that even the most novice boat owner would probably do a better job on their own boat then a boatyard laborer making $10/hr. He said we should ask around in our own area for what works best, and lasts the longest in our cruising area. It seemed "hands down" everyone thinks you get the most bang for your buck with Pettit Trinidad, but now we are having second thoughts if it will work over the paint we have. Anyone out there have any bottom painting experience that can give us any advice?

Thanks,

Carolyn

There's probably a lot on the subject in the archives, but I was told when I painted my bottom that only ablative should go on ablative, the reason beign that ablative is designed to wear away. You'll get more on this subject from others I'm sure, but just to be safe I wouldn't paint until you have a definitive answer. Also, if you do have to sand off the old stuff I'm pretty sure that you won't need to put on a primer for the new stuff. Once down to the gelcoat you can paint.

If the factory did your first bottom job your boat will already have a nosandable primer on it. It will either be black or gray. This will allow you to remove all your ablative and know when it done by the color change. Somewhere in the instructions for application on the SR can it will tell you what prep you have to accomplish before application.

It is my understanding that you can put a ablative paint over a hard paint, but you can't put a hard paint over an ablative.

Thanks, you guys are right. You can put ablative paint over hard, but not the other way around. We are going to use Pettit Ultima SR ablative paint instead.
