Gel coat cracking

I've noticed this crack just over a year ago, and probably should've dealt with it earlier, but it's grown since to about 3.5". I now keep it covered with blue tape which seals it nicely, but I believe it keep growing and the surface is slightly raised, so I assume some moisture has penetrated. I'm hoping someone can tell me a way to resolve this problem, and I'm probably not as concerned with post-repair looks as others might be. What should I do?

  • An old aviation trick is to drill a hole in the fiberglas at the end of the crack to stop it from spreading. Just penetrate the fiberglas and then seal it until a permanent repair can be made...I agree with the freezing water theory.
  • This area is the corner of the bedroom slide, which is what you see in the picture. Sure, it's easy to get to the inside and I can say there is nothing adverse to report. I suspect if the outer layers were pealed back, you'd see minor water intrusion. I guess the thing to do is a procedure similar to removing skin cancer - start cutting until all the bad has been removed, then start re-building. My question is rebuilding the fiberglass portion.
  • To me, that looks like water intrusion that has frozen swelled and cracked the glass structure.
    Is there anyway to get to this area from the inside? just to see what is happening ?
  • That is more than just a gel-coat crack. It appears to be cracked all the way through. You need to find out why this happened, before deciding how to patch it. I'm sure many body shops could do a repair, or give you some advice in repairing.

  • Possible frame failure underneath. Hopefully not. Is this crack up front in the vicinity of the pin box? (Lippert frame?)
