All I know, is that I never should have sold my NIB Sumiko methacrylic/lead/barium mat.
I never used it, as it was a one shot deal, due to the adhesive layer on the back. Once on the platter, that's it. And if you use an LP12, like I do, the two piece platter means the mat adhesive will bond to both and then it's a done deal. Removing it would be next to impossible, and that was part of how it worked. Part of it's function made it near impossible to remove once applied. I mean, the thing was like $400 near the end of the 80's early 90's. Hell of a mat....
