I recently refurbished an O'day 39 that was originally sold into the Caribbean charter
fleet. I don't know the name of the charter
company but the work they did was top notch.
One of the things they did was paint
the bottom with what appears to be a coal tar epoxy
. This stuff is as hard as nails and likely the reason the boat does not have a single
blister. It was so tough we could use silicon carbide for a medea to remove many many layers of old bottom paint
. The media opened the epoxy
up a bit so I applied several coats of Interprotect. The problem is that the coal tar epoxy was applied with a significant textured finish. We thought about removing it completely but the silicon carbide had considerable difficulty cutting through it and if it did I was afraid it would eat well into the gelcoat
before we would know it. And then there was the thought that one should not mess with success. It provided 30 years of blister protection.
The problem now is that I would like to smooth this texture out. I don't want to spend a month sanding
and fairing. I'm hoping to hit it each spring with a sander to get the hi spots and then apply another coat of bottom paint
. The boat is on lake superior
right now and will be in fresh water
for a few more years. Does anyone have a recommendation?
