I need Fiberglassing 101

[Mulv80]

I attempted some fiberglassing yesterday for the first time. I was attempting to fiberglass a new piece of wood that I epoxied to the fuel hatch in the floor. I was not successful to say the least. I first wet out the surface with West System epoxy. Next I laid out a piece of mat and brushed the epoxy on to the mat. The fibers in the mat were coming up with the brush and air bubbles were everywhere. I tried squeegeing out some of the bubbles but at this point I was frustrated and scapped the fiberglass and decided to try another day after doing some research and reading. This was the single most discouraging part of my project so far. I don't know if I will ever be able to glass in the transom. I really need a good source for fiberglassing info. Anyone know of a good site or book that I can buy.
