Looks very nice,just a quick question, what purpose does the pva serve and is this applied before or after wax?
Well, I'll give you my understanding of it. Those with more experience can correct me. The wax serves to provide a very slick surface so that the resin doesn't stick to it. It takes quite a few coats of wax in most cases. I think 6 - 10 is the most common number of coats. In some cases, the wax used isn't enough to ensure that you get a clean release without damaging the plug. The PVA serves as an additional barrier to aid in clean releases. It dries to form a film that peels away from the plug and mold and layups. Some folks don't like to use the PVA because it leaves a residue on the plug and mold and layups that requires cleanup, and may even permanently stain the pieces. The PVA goes on after the waxing has been completed.
Hope that helps.
