    Default fiberglass repair

    I have a 1973 dimarco 19' deep vee hull it is turned upside down now to repair very slight gel-coat blistering and to change the color. I am thinking about painting the whole boat rather than gel-coat and wanted to get input on both. Also wanted to know how to tell if this boat is polyester or epoxy layup. I am thinking it is polyester but that is only a guess Thanks for any help!

    To tell you the truth unless you are planning on using Epoxy for your repairs i would not worry about what resin was used ........but on the other hand i can almost bet that Poly or Vinyl was used in your build , and not to mention that if you paint the hull you will save your self a whole lot of X-tra work opposed to Gel .

    All Westcoast builders were using Polyvinly resins at the time.

    The bottom side of the hull looks good but will need the fiberglass repaired around the bow eye-bolt and 4" ahead of the rudder. And around the rudder . The eye-bolt had worked loose and elongated the holes in the fiberglass , at the rear it looks like the prop might have broke or came off and hit the hull. Both should be easy to fix they are about 1/4" deep . I was not sure which resin to use I thought polyester would be fine but not sure? By the end of this weekend I should have half the gel-coat removed from the bottom . the raw fiberglass looks real nice after block sanding . Thanks for the reply's and any input. Sangerbuzz
