Thanks for the replys ,
Yes good news Joe
I think its going to be a goer
Have filled the cracks with the new black gel coat ,,
You now owe me a track lap in your carbon fiber Dolomite
Joking... but happy it turned out good.

I believe your cracks are the result of having your gelcoat too thick, any bending of the mold will crack thick gelcoat.
The best way to fix it is to V out the whole crack and then mix up some of the same gelcoat you used and build it up layer by layer. If you get gravity
on your side fill the crack just barely and put a tightly stretched piece of clear packaging tape down over it. It will flatten things down quite well. Once cured you will have to carefully bd sand the repair down flat and polish. I use 2 or 3 inch pieces of paint sticks.
Another thought. You will wax the mold on your next part anyway so wax will seal the crack. Your part will have a slight crown which is easy to sand down.

As already here really. Although its also very easy to repair really minor cracks in moulds using super glue. The same why you can secretly repair repair carbon with basically.
