You have the slow, medium and fast mix of epoxy and that is dependant on the climate. Slow in the summer is ok but has a mind of it's own, fast in the summer may catch you by surprise. Slow in the winter - oh my, it could be a week, while fast may be a day. You have to experiment and waiting too long for it to totally cure is never an issue. Better safe than sorry.Now, Poly has a short fuse as per time.....You end up hoping it will not set before you are done laminating!! Epoxy has much more cure time.
Man you're really moving along. Don't look like the rain here has slowed you down.
