I was reading the replies to the article "Fiberglass problems and Blister" and noticed Crazy Dave talking about vinyl ester resin in below water line repairs. A couple of weeks ago I was out sailing my 1994 23.5 and bounced off of something. We were in the Chehalis River at the time and I assumed it was submerged log/tree/root wad and was just happy it was not a dead head. The blow was pretty light, but when hauled the boat out I found about a two inch long nick in the gel goat below the water line. I was getting ready to fix it this weekend when I read article that mentioned the vinyl ester resin. What I was planning on doing was cleaning out the nick, roughing it up with about 80 grit sand paper and then using an epoxy putty to fill the nick. I have done this on other boats and I have found that if one uses plastic over the putty it is possible to get a nice smooth finish that does not require sanding. Of course this was always in Polyester resin gel hulls. Anyhow, my question to Crazy Dave is: 1. Does a 1994 Hunter 23.5 have a vinyl ester resin gel coat below the water line? 2. Is the repair technique described above appropriate? Thanks, Al Beattie "ElseWhere"
