I did a laminate test to check out color bleed (used the Futura acrylic as a thinner) etc. on a cut-off from my blank using 1 - 4 oz layer of e-glass. I was surprised that I could crush the lay-up so easy with my thumb, so surprised that I couldn’t believe that 4 oz would be used as a single layer. Silmar 249 @ 1.5%. Any insight on this one?
4oz is weak, but you have no side support, making it seem weaker than it really is.
A single flat lam always seems weak.
