My 100gr/m2 chopped strand mat is on its way. But i've already applied the gelcoat on to the pattern (which is pretty complex shaped) surface. I've seen in the tutorial videos that the best way if you leave the gelcoat for several hours to cure before you applie the coupling coat. My question is: 1-2 overnight is still okay or it is a bit too much?
Shoud I continue the work with 225gr material which I have on stock?
Thx guys!
