Hello All:

Trying to find the discussions on "seperating rub rail" that was discussed about six months ago - can't seem to find it now - anyone remember key words that I can use in a search ? Rub rail" did not get me there.

Blisters - I have a used 2001 22 foot C-dory. I keep it in the water from May to November. I am thinking of stripping the bottom paint and applying a barrier coat - looks like a big job - Blisters a 'heard of" problem on C-Dory's?

Thanks

Ken
 
When I redid the bottom on my ole tug, if I remember correctly the barrier coat was just a layer of resin....then the bottom paint was applied over the barrier coat.... I would think that the gel coat on a C-Dory would be the barrier coat and the bottom paint could be applied directly over the gel coat... the resin coat was to seal any spot that was poris in the original finish....

I have never heard of anyone with a blister on a C-Dory .....ever.

Wasn't there a case about a year ago where someone had a case very small "blisters" in the green colored gel coat. It seems that the answer from factory(Jeff at the time), was that it was cosmetic, but I think they did fix it. There was a big discussion about it, but I can't find it now, so I maybe just dreaming.

The long discusion of blisters is under the topic title: Should have gotten a Bayliner. Hard to type that. My "pimple" blisters have not changed so I am not concerned although I did quit pressure washing.
 
There have been several boats with "Blister" reports. Some appear to be more defect in the gel coat than true osmotic blisters.

Either way, as long as there are no blisters on the bottom, then stripping the bottom paint is not an easy job. There are several ways to remove the bottom paint. Chemical strippers, soda blasting (needs a real expert, because even soda blasting can damage the gel coat--sand blasting is a "no no".) and sanding. After the paint is off (there can be residuals in scratches), the bottom needs to be sanded, dewaxed and then 10 to 20 mil of epoxy built up--usually 4 to 5 coats will suffice. The epoxy is much less permiable to water than gel coat. Modern C Dories are susposed to have a layer of vinlyester resin under the gel coat. But the factory still suggests that epoxy be applied on boats which are kept in the water.
