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.

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.

...OK, but PVA is water soluble - wouldn't 10% PVA in vinyl mean that you simply can't wash these records without making the surface dissolve?! Or does the 90% PVC cancel this effect? (I dropped Chemistry!).

Cheers,
David.
