Hi folks,I bought my Catalina 310 brand new 3 years ago. It came with Pettit Trinidad Pro hard bottom paint on it. The paint lasted quite well for 3 years in Sarasota, FL bay waters. I had a diver clean the bottom each month.Two months ago, I had it re-painted at the same boatyard that did the original job, with the same Trinidad Pro paint. Swimming around the boat, I used a sponge to wipe some slime off the waterline and the sponge turned solid blue from the paint rubbing off. This never happened with the old paint...not a single bit. My diver, who does this for a living full-time, noticed the same thing and said that it sure didn't act like a hard paint to him...more like an ablative.The boatyard and Pettit rep said it might be a "soft" batch of paint, or else the formula for Trinidad Pro may have changed, making it less "hard". They've agreed to re-paint it, but said there's no guarantee the new paint will be any different.Has anyone else encountered a similar situation? Does it make any sense that a paint advertised as a hard paint should wipe off with a sponge? Am I being fed a line?Thanks,Cliff
