cheap tweak for glass platter 'tables

I was browsing at my local Harbor Freight Tools store the other day and was intrigued by the properties of a "tool box liner" (item number 90982 at harborfreight.com) that they had. It was only a couple of bucks so I bought two of them. Then I got to wondering if it might make a good mat for my Systemdek IIX. Since I don't have VTA adjustment, it needed to be the same thickness as the stock wool mat and it was. What the heck - I cut one out and wow, I really like what it did to the sound! Tighter, but more defined bass. Better imaging, etc. It's very tacky (in more ways than one) so it sticks to the platter and the record sticks to it, so no need for a clamp. It doesn't leave any kind of residue (so far). I love cheap tweaks that work!
