I did a little more research on Road-Kil yesterday.. I keyed the name in wrong is why the product did not come up, the actual name is STINGER- RoadKil.. They have an extensive sound control/deadener line, hood, trunk pads, insulators for speakers, etc. The sound control mats come in several sizes, the best buy being the 18"x 32, 36 sqft per carton. The price varies from vendor to vendo, a low of $104. up to $128. The $104/128. is for the RoadKil Expert which is .080 mil.
I ordered a carton of 36 sq ft, 18 x 32 'Expert', $104. free shipping. Wm.
