I'm about to start doing some fiberglass work and I'm wondering if anybody has a good rule of thumb for calculating how much mat/cloth and resin you need for a given size box. I've done some fiberglass repair work but never built anything from scratch. Any thoughts?

1 gallon of resin for sure, as for mat I would probably order about 8-10 yards to be safe.

Ok, just for an example, let's say I want to build a 2 cu. ft. box. About how much would you say I need for a good solid box. I know it's going to vary with the shape and speaker holes, etc. Just wanting to avoid having a lot of leftover material because customers won't like paying for that nor will I.
