: Another two questions about Fiberglass.

: I'll most likely use 6 oz E-Weave as my main layer. There are some areas
: where I want to do some extra reinforcing, as seems normal. So, in
: figuring out my combinations, is there a difference between, say, 2 layers
: of 6 oz, versus 1 layer of 12 oz?

I think there is a difference. If the fiberglass were equally strong in all directions this might be true. However, since that is not the case I think your assumption is false. The reason is that you can put the two layers on at slight angles to each other. This will definitely have different strength chracteristics (but I don't know if it is stronger or weaker or both depending on the angle)than 1 layer.
