Jim: I should have noted in my response that stripping the hull
and sealing the vertical keel
joint were not related; the hull
stripping was done for other reasons; my horizontal joints never were a problem but I used the same Gluvit stuff there just in case. The vertical joint really bothered me and it could be sealed using the Gluvit and fiberglass
tape very easily.
I was impressed that the Interlux
barrier held up well over it, but even if it did not, the Gluvit also is an epoxy
barrier. Best of luck with the Hughes
