Vinyl Cleaning: Device to keep label dry?

I have some rough vinyl that will require more than a damp brush to resurrect. I will need to immerse the platters in soapy water. I thought I saw somewhere some kind of device that clamps onto the record, encircling the label and sealing it from water damage. Maybe it had a silicone gasket type material where it holds onto the record.

Anyone know what I saw, or was it another weird dream?
