 ......Just mask, wet out the fiberglass tape with gelcoat, unmask, let
cure,  remask, sand a bit, and apply a second layer of gelcoat to smooth
things out. Just make sure that if you're not using finish gelcoat to
brush some mold release over it after about one hour to let the surface
cure fully and not be sticky. It's really a lot of fun!


Hi Duane, Philip,

There is another nice trick to avoid the stickiness of the brush applied
gelcoat after it has cured. If you just add a drop or two of liquid or
melted wax into the gelcoat when you apply the catalyst, the wax will go
to the surface during the curing process and prevent the gelcoat curing
under oxygen atmosphere from the air, and then it will cure OK and won't
be sticky.

You want to do that only on the final layer, because if you do it on an
intermediate layer, you'll have to sand the wax away before applying the
next layer or it won't bond.
