Re: 1972 Blazer CST Frame off Project in NC

Speaking of firewall and applying a dynamat product - has anyone that done it have any tips? Any areas I should avoid or advice? I wasn't sure if I did everything that all parts would go back in ok - like the brake pedal assembly, e brake assembly, etc.[/QUOTE]


Trucks looking great!

I used a similar product "Second Skin". Here are the install steps they have on their website.

Make sure to clean the metal with denatured alcohol. If you use a degreaser you will need to clean the film left behind off with soapy water and then wipe down the surface with denatured alcohol for best adhesion.

Trace out the area you are applying the product to with cardboard or paper and then transfer that to the butyl Damplifier sheets to cut out a perfectly fitting piece (or freehand it).

Place the piece in the desired location with wax paper still on the butyl sheet to make sure it will fit, as the butyl is very sticky and once the wax paper is removed it will adhere to surfaces for a permanent bond.

Now, remove the wax paper and place the butyl sheet down upon the surface, working your way from one side to the other or from the center out to the edges.

Once placed down, take your wooden hand roller and push the butyl sheet to the metal to form a nice bond over the entire sheet. If you have a concave, groove, and/or ridges you want to work the product down and up those valleys with the wooden roller or the back side of the wooden roller for the smaller dips.
