I found myself a decent dash pad that has only a few minor cracks in it for my c900. I'll be replacing the blower motor and fixing the vacuum leak I have in the air distributor switch while the dash is apart.

I've had the dash torn apart before and noticed that the 30 year foam that seals the various HVAC duct work together has crumbled into nothing. The system doesn't blow as much air through the vents like it used to.

Does anyone have a source for a good foam replacement material like the OEM's use?

I finally found a suitable material on the McMaster-Carr website. Should be better than the original material.

From their website:

"Also known as polysiloxane, this material maintains its flexibility across a very wide temperature range and is a good electrical insulator."

Color: Orange-tan
Temperature Range: -100° to 400° F
Firmness (25% Deflection): 6-14 psi (soft to firm)
Density: 29-48 lbs./cu. ft.

Cool!

Nice, I was wondering if there was a solution for that stuff. Mine is pretty powdered as well. Bookmarked for when the dash goes back together.
