Holy catfish! Rip van Winkle here. When I took my first comprehensive kayak course in the early 1980s we were taught how to do our own fibreglassing. Not difficult and I’ve done it ever since, including Kevlar. You do need to do it outside on a relatively warm day. I must admit that sometimes my boats did look a bit like a dog’s breakfast, but they never leaked and I could make repairs even on trips. In fact, I always carry the makings of a repair just in case. If it is cold, you may have to make a fire to get the stuff to go off. Your boat isn’t really broken in until it has a few scratches and at least one repair. Seems to make it go faster.
