Gel Coat Crazing: Sudden Appearance
Posted: Mon Mar 25, 2019 11:59 pm
I had my 1963 Sport 13 upside down in my backyard for the winter as I rebuilt the trailer. The hull had some poor bottom paint, but the hull was in decent shape. I was planning on repainting the deck. On Monday, March 25, 2019 I took off the cover. I saw the entire port side has some crazy crazing and cracks that weren't there in October 2018.
I don't know what happened. The inverted hull was on blocks and covered with a regular canvas boat cover. The crazing didn't happen to the other side. The side it happened to is facing South, facing the sun. I'm guessing that there was too much heating and cooling, expansion and contraction of the fiberglass, and that caused the gel coat to crack.
What is your guess?
Now I may be repainting the whole hull.
Any suggestions [on how to repaint the hull]?
I'm not planning on making the boat true to original. I just want a decent fishing skiff. I'm may use Total Boat epoxy primer and Wet Edge, and apply using roll-and-tip. I may use Total Tread Non-skid.
The boat is trailered.
Would AWLGRIP be better?
