Sand down a bit of the ablative paint until you can see what's underneath it. Hopefully underneath there is a layer of paint, usually grey, that would be the epoxy barrier paint. If so, I'd just get as much of the ablative paint off as possible and recoat. If there's no barrier paint, I would seriously consider removing the ablative paint completely. I talked to an Interlux representative at our local West Marine that was having a big tent sale. He said that he recommends a light sanding of the gelcoat, just enough to give the barrier paint some bite. Apply 7mils thick of the 2000E and then use bottom ablative paint. I think the key here is whether the PO used a barrier expoxy primer. But here's another thought. I keep SeaFrog in a slip nearly all year round. I used to keep my NorSea 27 in the water year round. The PO on the NorSea did not use a barrier coating. The last time I hauled her out, she had over 250 blisters the size of a quarter. It didn't present a problem of it sinking but it looked ugly and obviously slowed her down. The question that I don't have an answer to is this. If you pull your boat out for the winter and the hull dries out completely, is the barrier paint necessary??

Since nobody answered I thought that it might have got lost in the mail so I'm giving it one more try.

My boat was kept for two years in salt water by the original owner, who painted the bottom with a copper-colored ablative bottom paint. I have trailer-sailed the boat for almost four years in fresh water, and the paint is now showing its age, besides making a big mess when washed with On and Off. Does anyone have any advice about how to remove the old ablative paint and what it should be replaced with? I was thinking of sanding, but the recent posts on gelcoat damage from sanding are making me rethink that and ask for help.
Thanks,
