[C320-list] Hull prep

[Allan S Field]

As further evidence of the lack of blistering with these boats, ours has
been in the water for 13 years, coming out only every 2 years for a week to
paint.  And the boats in CA are the same - they come out only for painting
and go right back in.  The money I save in hauling and land storage, of
course, goes back on the hull to once again slough off into the Bay
prematurely! - 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.
