I found a few sites that had it, found one that was selling it by trukloads .30 per roll, but you had to buy 10,000-12,000 rolls
I scurried on about to another site, I got a sample board getting sent to me with all the foams they got, Oh joy! more foam to play with.Those same guys also sell hard rubber sheets I'm thinking door panels!!! closed density foam from 2.5 lbs per square foot to 55lbs per quare foot, center consols and doorpanels and dashboards OH MY! Havn't found anywhere that sells it retail, like a small interior shop or anything, just the big time guys that sell 150' rolls but I'm stepping lively, I'll let you know if I find anything.
