I have not tried the EZ-Lam I usually use proset, its it the same viscosity as proset? From what I understand you bag your glass or carbon into the mold then a valve gets opened from the opposite end of the vacuum and it wicks the resin through another tube, sounds like a good way to may parts even lighter. I don't know if this Poly c is what I am thinking of I think this stuff I was told about uses a hardener, I will look into it and Epo Thin also.
