I put 7 coats of Interprotect 2000E on the bottom 10 years ago and the
bottom is fine......don't apply a barrier coat immediately after
haulout......let the bottom dry for 6 months.
There are lots of boats at our club that have had the same thing done
with no problems. Like most jobs, if it's done right, there should be
no problem.
One of the local brokers, Ocean Yacht Sales, uses a barrier coat on
older boats as a 'sales feature' to prospective clients. I had my boat
surveyed last week (insurance required) and the surveyor felt the
barrier coat was a 'positive' not a 'negative' when told how it was done.

I spoke the yard today about barrier coating. Their experience was it
trapped moisture which causes the barrier coat to fail.

I am planning to strip all the old bottom paint off this fall and
repaint in the spring. I have two questions for the list:
1. I have two quotes now- the higher uses walnut shells and the
lower uses crushed recycled glass in water. Both claim gentle on
the gelcoat and little followup prep needed for painting. Anyone
have any comments or experience with the two technologies?
2. I had originally planned to barrier coat before bottom
painting, but the last time this issue was discussed, it seemed
that for a 1990 era C&C, it should not need barrier coating. That
would dramatically reduce the amount of painting next spring if I
don’t need to put on multiple barrier coats. Do people agree that
it is not needed? Compromise of a few coats? Thanks- Dave
