One of the things I learned over 30 years ago that causes premature epoxy tooling life is allowing razor knife cutting on the mold surfaces when utilizing pre-pregs or wet layup for that matter.

That is a statement every fabricator should put on his wall! It will destroy the edges of a mold quick. I was taught that method and changed to making a template so I can cut the glass to fit the mold without post trimming.
