I've also used this method many times and once you get the hang of it (ie. leave for 24, or even 48 hours, and make sure the covering is 100 percent on the play area - into the runout but not up to the label, and right up to the outer edge), then it works great.
It should look like the picture from Russ. Solid white / cream when it is wet, and going clear when it begins to set. See about 3 o'clock on the One-Derful record. If, after a long time you still see a single spec of white, don't touch it, just wait until it is fully clear. When done, gently tease off a start on the outer edge and it should peel off. If it flakes and little bits stay on the record, just recoat it and the flakes will bond with the fresh glue.
Remember, this is a deep clean method, it won't repair damaged records.
Cheers
