Do you guys think 100 sq ft of this stuff will do my regular cab plus the fire wall? Its a 219 bucks but I think it should be worth it.

 

Not saying you don't know, but in case you don't, it's easy enough to calculate square footage. I don't know if you're wanting to cover the floor too, but just in case, all you need to do is measure 2 of the 4 sides. So for the back wall, you'd measure from the driver side to the passenger side and top to bottom. You don't need to be exact- in fact, I would record the longer measurement. So if, for example, the back wall is 4 1/2 feet from top to bottom, I would count it as 5 feet. Then if the back wall is 5 1/2 feet, I'd count it as 6 feet.

Then 5x6=30 square feet. Repeat the process for all sides of the cab you want to cover plus the firewall and add up the numbers and you get how many total square feet you need. Overestimating would also help account for waste and/or mistakes to a point.

I wouldn't count on 100 square feet covering the whole cab plus the firewall but I don't know the measurements of your cab either.

 

thanks a bunch think I might start with 100 then get more if I need it

 

$220 seems kinda steep for fatmat
Amazon.com: 100 Sq Ft FatMat 50 mil Sound Deadener w/Install Kit: Automotive

 

the reason this stuff is more is because it is not made of asphalt, it is made of something called butyl, I guess its supposed to be more heat resistant and alot better product

 

I used tite seal... Its alot cheaper and works great

I have 2 layers on the doors and 2 layers on the cab wall. When I get some more ill do the roof and floor. Should be about 5 of the small rolls to do the whole truck.

I bought a big roll 2 weeks ago and a sheet of plywood and threw it in the back like a DA and got home and it wasn't there.
