Thanks for the great how to!!! What's the gallon of resin you are using? The one you linked to has some bad reviews like not curing completely and staying sticky.
ebaysurplusauction I’ve had success win Alumalite in the past, but I did bake it or leave it in the Arizona summer sun. The gallon jar I’m using is from a local store but if you have a Home Depot nearby is recommend bondo brand.
