I just have a quick question which may just result a simple answer...or not.
In my search to locate a reliable method of applying fiberglass to a rocket, I wondered what the differences in the actual hardener and resins may be. (From what I do understand, the weave of glass measured in ounces is based on density and just that, weight or thickness.) I was at Home Depot the other day searching for their fiberglass solutions and came across the "Bondo" brand of hardeners and resins. I read over the labeling and the settling time is about 30-35 minutes. Granted, I would never use an automotive grade of fiberglass weave on a rocket, but what about the actual epoxy mix? What makes the hobby grade different from say, a commercial grade or automotive grade epoxy (hardener/resin)???
Thanks in advance....
PS - My initial use of the resin/hardener will be with the stretchable nylon material. I will get into actual glass weave later.
