I tried a couple of LPs with whatever wood glue I had lying around and it worked OK. Getting the peel started is a little tricky but it came off all in one piece pretty easily. The peeled glue looks like a papadum with the center missing. The glue I used was Elmer's wood glue but I ran out so I picked up a bottle of Titebond and this stuff won't peel at all, it is brittle and breaks as soon as you start to lift it. Luckily, this disc was from the $1 bin and I can play the other side that was cleaned by Elmer's.
Is it due to the different glue or user error? I might see if you can get Elmer's in a bigger bottle. I planned a little shoot-out between glue and my RCM to see if I get better sound from one or whether it will be a wash (NPI).
