I can't tell y'all how many boat building sites I have looked at. What I can tell ya, not that you will pay attention, is that there are lots of different ways people make boats.
One of the things I have seen is, those who advocate a strile shop prior to doing epoxy or varnish work. There are folks who , in my opinion, go to extreams and are parinoid about a bit of dust getting on the boat.
NOW, if you are building a boat to sell for $4000 + perhaps I can accept that. But, in my little world, I build them for me and for use. They are going to get scratched, dinged and gouged. There will be dirt, limbs, garbage, fish scales and about anything else you can name in and on them.
I therefore don't worry a lot about dust and bugs. Basides, what self respecting boat dosen't have a gnat or two entombed in the epoxy.
That being said, I got the outside glass on with the first coat of epoxy.
As any fool can plainly see, I have trouble with the stem areas. I do my best to get the glass cut and placed nice nad smooth. But, in the end, I always have to sand a bit and put another piece over the stems. I do that anyway just for the protection. I run a piece from the top of the stem down and under the boat for about two feet. That is the part that normally takes the worst beating and a bit of extra protection there is always welcome.
