[C320-list] Hull prep

[Allan S Field]

OK, you now may want to talk with Catalina.  The hull is layed up with
vinylester resin rubrail to rubrail, versus the old polyester resins that
blistered.  There was a bad run around the 400 series of about 100 boats of
which some had some blistering problems but that is all I am aware of.  Hull
#1096 is way outside of that range.  Everything I have ever heard from
Catalina is that a barrier coat is a waste of money.  The bubbles most
likely are in the paint which can be scraped down.  Let me know what you
find! - Allan

Alan, it's about 8 years since new. The layers are looking very patchy, and
some minor bubbles have appeared. I believe it is recommended to strip back
to gel coat every 10 years to check for osmosis.
Once stripped and checked, we will apply a coat of epoxy sealer prior to 2
coats of micron 66.
