Stop in for a cup of coffee

What kind did you use? I now a lot of guys use whatever Home Depot has. Apparently similar to Dynamat at fraction of price.
I bought some off ebay. It wasn't real cheap. I think 20 squares was $100. I used like 6 and sold the rest. You can look and find fewer than 20. I'll look and see if I can't find what I bought. Sure Lowes or HD has something cheaper.
