Fiberglass hairline crack repairs?

Question

Darned if I didn't hit a tree backing into a site (front side) which caused some hairline cracks in the fiberglass. Also have some hairline cracks on the sides of my slide (stress related?).
They don't appear to be very deep, but I can see the black past the gelcoat. Fixes to keep water out?? Paint, caulk, or just plain fiberglass wax??

If you prep it correctly you can do a decent self repair on a verticle surface with Plasicoat....tape off the area for overspray, do 2-3 light coats of white Plasticoat, then one coat of Glossifier......it will blend OK and keep water out....for horizontal surfaces it will also work but there are other options....

If hitting the tree cracked the gelcoat. Maybe you should get it checked to see if it cracked the glass as well. Glass often moves with the gelcoat. If it cracked one, it could have cracked both, and not fixing it correctly could be costly in the long run. Think water getting to the wood laminate. Bad thing

The black you are seeing is the fiberglass.

There are plenty of fiberglass and gelcoat repair kits out there. I have even seen them in Walmart and HD. Should be an easy fix with color matching the biggest issue for you.
