I hate it when people answer a question I did not ask. Yet here I am, doing it myself.
I just attended the EAA Fiberglass workshop for RV's in Oshkosh. It was excellent!! It totally demystified fiberglass work for me, and it focused only on the things an RV builder will encounter. It was well worth the cost and travel time.

Here's a partial list of topics we learned (and practiced hands on) that were invaluable:
1. How to layup the windshield to aluminum transition. Scott teaches a method that is different than the Van's instructions. In my opinion, it is much easier.
2. How to make your own "pre-preg" fiberglass material (GREATLY reduces mess and makes a much prettier part)
3. How to use Dacron "peel ply" for curing that will cut the need for sanding to virtually nothing.
4. A long list of which products to use, and when (micro bubbles, flox, Aeropoxy, etc...). I had heard many of these terms, but didn't really understand which to use when.
There are many other things we learned that gave me the confidence to work on these parts.
Not sure when this class is offered again, but for anyone who is considering it, I highly recommend it.
