The guy coats a record in glue, waits for it to set, then peels it off. Apparently it works very well. I'm not sure how it compares to other techniques, so I figured I'd run it by you guys and see what you think.

1. Attack the argument, not the arguer.
2. Assume good faith.

There are a lot of different PVC glues with various ingredients. I would be very cautious.

PVC glue would mean a 100% record destruction guarantee, that's why PVA glue has been recommended... wink.gif

But I would also not recommend to use this method. It may work with very old pure PVC records, but for a couple of decades vinyl records are being made of a PVC/PVA copolymer (about 5-15% PVA). At the time of pressing the shorter chained PVA molecules even move preferably to the outer surface. So if you are unlucky you end up with an inseparable PVA/PVA bond in the end.

hehehehe yeah. I meant PVA sorry. I think the confusion over water solubility is due to the fact that there is PVA Polyvinyl acetate and PVA polyvinyl alcohol. Polyvinyl alcohol is used as a seperator for mold making and casting involving fiberglass and other resign based molds and castings. That PVA is water soluble after it dries. Ironically it does not thin with water like Polyvinyl acetate.
