Felt? Now that's not very utilitarian.
It's 1/4" heat compressed granulated rubber. Nothing slides on this surface.

 

you made it ? where can i get that stuff ? i think there is still a rubber and gasket co near me...maybe they got it ?...i got the gm rubber 1 but i'm saving that for my funeral....half my ashes go in the hhr and the other half go in my 67 fastback

 

I really like it, so you made it?

 

Is the rubber like what they use in horse trailer walls?

 

Come on, give up the info! You made it? Out of what?

 

Yes, I made it. I couldn't find what I was looking for at the time.
I purchased a 48"X 11' roll (min order) from a rubber mat manufacturer I found on the net.

They also have all kinds of colors, just be aware they have a minimum order and this stuff is on the heavy side, so shipping could be substantial.

FYI-I still have the other half of the roll, if any one is interested, PM me. Official HHR mat manufacturers of this nature were going for around $120 + frt when I did find them. Think half that

 

Hummm,
maybe its time for "LINE X"
