Questions & Answers Ask a Product Question

Will this adhere to areas treated with LizardSkin (rough finish)? And will it be an enhancement to the effect the LizardSkin provides? I guess I’m asking if anyone has ever used both materials with any success?

How much do I need to do the entire inside of a pickup truck cab (firewall, floor, roof, back of cab, doors)?


Asked by GREG on January 13, 2019


I applied it over Herculiner and it adhered just fine. For a regular cab '70 Ford pickup I had to buy a bulk kit(DYC-10455) and a door kit(DYC-10435) and it covered the firewall, floor, roof doors and up to the back window with just a little left over. I didn't put any under the bench seat however. Made a huge difference in how solid the cab sounds. No more sheet metal echo when shutting the door.

How hard is it to remove the sheets after they have been installed for a decent amount of time?

Asked by MIKE on December 29, 2018


Just scrape it off with a gasket scraper or screwdriver.... im welding a new tranny tunnel for my T56, and had to clear out the dynamat where im welding... it comes off pretty easy, if you apply heat even eiser!!

Asked by EDWARD on May 02, 2018


This is not an insulation or insulator. It is a thick sticky mat, kinda like tar in a sheet, that deadens the tin sound your metal panels make, and most road noises.
