Not familiar with the method you are using. Way back in the day I had very mild success sandwiching a record between two heavy plates of glass. Then setting it outside in the sunshine. As I can no longer find the plates of glass I used, I suspect it may not have been as effective as I remember or just that I begun too make the move to CD's.
any success with "Vinyl flat" and warped records
Has anyone had any level of success using the "vinyl flat" product in conjunction with there "groovy bag". Tried it on three different mildly warped lps and left two in for as long as 24 hours and have zero success. Any suggestions before I stop wasting my time?
