Our overland camper is built on a Fuso medium duty truck chassis. The cab-over configuration places the engine between the driver and passenger. As originally configured, the cab had no sound proofing or heat insulation, making for a loud and often very warm cab environment. I had a phone conversation with Second Skin and received some helpful suggestions to improve the situation. I installed Damplifier Pro sound deadening mats on the floor of the cab, under the OEM vinyl flooring. Mega Block hydrophobic foam heat shield was installed under the cab, above the engine. I was concerned that the half-inch thick Mega Block would be difficult to install because the area was composed of complex shapes with many curves and several control cables to work around. It turned out that, working carefully, the Mega Block could be formed into the complex shapes reasonably efficiently. The adhesive on the back of the Mega Block sheets is extremely sticky, so I had to tactically plan to when remove the backing once I had the sheet mostly in place. Four sheets (16 sq-ft) was adequate to completely cover the underside of the engine compartment. The front wheel wells are immediately below the driver and passenger seats, resulting in considerable tire and road noise. Spectrum was applied to the front wheel wells using a paint brush. I applied four coats totally about 4 mm in thickness. Applying the Spectrum was straight forward and cleaning up with water was easy. I am very happy with the results of the above installation. Excellent products and great support from Second Skin.
