it's called Van-gard. :) and it's made by 3M. you can get it at
RV suppliers (but they usually have only the largest size ... it
comes in 6x8, 8x10, and 10x12) or automobile body shop suppliers
(the folks who sell the bondo to the fender fixers) who carry 3M
products. jcwhitney also carries them. they run about $10-15 and
are well worth the money.  :)
