I'm getting ready to remove the very old, thin, and worn out antifouling on my F235. I've researched the various ways of getting the antifouling off (none appear to be particularly pleasant!), and have almost decided on the Peel Away product. I emailed the makers and learned that 'Peel Away 1' is sold through paint stores, and is identical to the 'Peel Away Marine Strip II' product that they sell through marine stores (but not mine!). This stuff is recommended (acc to their webpage) if one wants to preserve a barrier coat that is on some hulls underneath the antifouling. They said that 'Peel Away 7' (from paint stores) is the same as 'Peel Away Marine Strip I' (from marine stores), which appears to be harsher than Strip II with regard to barrier coats. Now for my question ... Do I actually have a barrier coat?? I don't have any idea what a barrier coat is, whether or not one was ever aplied to my hull (1989 model year), or even what to look for if I want to try to determine this myself. Does anyone know if Beneteau hulls of this vintage (and especially F235s) all had, or did not have barrier coats? Alternatively, how can I inspect my hull to find out if I have on or not. The Peel Away products are rather pricey, so for that reason, and not wanting to screw up my hull, I should find out before lashing out and getting Peel Away 1 or 7. Thanks, Neil
