Working for an airline, I can get fiberglass cheap-cheap at work, but I'd have to order it from Atlanta. The only problem is, I don't know the weight of what we have available.

I have a MIL-SPEC part number, MIL-C-9084-C, but the description I have is: "Fiberglass, A-finish class 1 and 2 type 3, satin nbr 120, 38 in wide". What does this mean? Is this 6oz or 4oz? Can anyone look this part number up somewhere and help me out???

Thanks,

Scott.
