I have been brushing on the surface coat and allowing to tack and then follow up with a very light weight woven glass. I lay a few layers of the glass on and then follow with incrementally heavier woven glass. The tooling and laminating resin are compatiblae and state a working temp as high as 350F without post cures if allowed to cure at RT for a reasonable length of time. This is great since I won't ever venture anywhere neat these temps. Regarding my laminating layup, I was doing this to prevent print through. Any insight into the validity of this technique? I'm leaning toward the belief that this is not what will save the surface of a mold since it is the serviceable temperature of the resin that would dictate the if print through happens if the Tg/HDT is surpassed. Any ides if I could just use a epoxy specific CSM instead and not sacrifice mold durability/quality?
