Rated 5 out of 5 by from Money well spent I'm very happy after all the effort i put into sound deadening and insulating my 1968 F100. It is painted black as as I finished in the driveway it was parked in the sun with temps in the 70's. I couldn't hold my hand on the outside of the roof while the underside was just warm.

Rated 5 out of 5 by from Nice product. This insulation is of nice quality and easy to install. I saw several comments concerned about the advertising on the product but that lettering wipes right off with a rag and some lacquer thinner.

What's the difference/benefits between this and the eastwood underhood thermal accoustic mat?

The xmat brand is 1/4 thick and the thermal mat is 3/4 thick which will be thicker to reduce more heat.
