Dynamat Installation

[340_6pak]

I need a little advice here, Ladies and Gentlemen.

The old carpet of the challenger is in the trash, and the seats are out. I have mat to install, and I have gone over all of the surfaces with acetone. The directions for the mat say to elminate all air bubbles and be sure that the mat sticks everywhere on the floor pans. The issue is with the floor pans. They have these grooves in them put in by the manufacturer that add to stability of the sheet metal. I think they are called beads.

Anyway, if I lay the mat down and go over it with the roller, it isn't going to go down all the way in the beads and the air pockets are there. So, my question is, is it worth it to take the time and cut the mat into exact pieces, or is it enough just to lay it over the floor board and press it down? I am thinking a 3 hour job vs a 10 hour job?

I am not looking for a whisper quiet cabin, I want to hear the 340 6 pak and the flowmasters.

What say you?

been there, done that. Use the roller where you can, use a stiff plastic wedge or bondo spreader to work it down flat in the crevices and low spots. It actualy stretches pretty well and lays down nicely. I think you will be impressed with it.   

Mak sure you have treated all your rust before you start laying it down. I stripped mine, then POR-15'd it before i dynomatted it.

  Great job. how long did that take?

[miketyler]

That didnt take long at all, the firewall and cowl replacement was not as easy.   

I used the purple anodized paint from Duplicolor just for the Dynomat that was visible above the carpet line.

Use a hair dryer to warm the Dynamat, it tends to be more flexable and conform to the nooks and crannies better.
