Last week I posted a question about my plans to barrier coat my 1987 WK this spring. Today a friend mentioned that there is a good chance my boat came barrier-coated from the factory. Is this correct? When did Catalina start this practice and how do I know if my boat already has this protection.
If it is already coated, how do I remove the old bottom paint without damaging that barrier coat? Thanks again.......

Nate my 2002 did not come with a barrier coat. That is unless a barrier coat is clear? I had to have it painted for extra $$. I will have to check my manual but I don't recall anything about being barrier coated at the factory.

I have heard that about this year Catalina switched to a vinylester resin so as to help prevent blistering.

The later edition owners manuals talk about factory applied anti-blister coatings starting in 1988 and cautions about over-enthusiastic sanding during prep for bottom paint.

If it's an epoxy coating, it may very well be clear. Other than performing some sort of chemical test or other examination of a hull scraping, I don't know how you could tell for sure if you had one or not...

Anyone out there know of an easy way to tell if you have an epoxy coated hull?

If you do find you have a (from the factory)Barrier coat why do you want to strip of all the bottom paint ??? I can understand if your going from salt water to fresh or want to remove it and not re aply it because you race. Perhaps there are a ton of layers already on. But if there are only one or two and you have no blisters I would just sand or rough up the bad areas and re coat the bottom with another coat.
