Hi all,

The foam insulation under my driver mat isn't looking too good (see pic).

Can anyone advise how I go about fixing this and whether the foam/cardboard piece can still be purchased? If not what would be a good replacement?

I haven't investigated in much detail, but I'm told (thanks Keshav) that there are sound deadening tar mat below this? Should these be replaced as well? and again same question can they be purchased?

Basically any help advice would be much appreciated.

I've a 74' CSi just in case that makes a difference…

Thanks in advance, Michael.

I removed my sponges (I mean foam) as they are moisture collectors. Yes under the foam is a tar sheet. I removed the foam pads then used a metal putty knife to remove the tar which came off easilly in sheets. Then I cleaned the metal, coated with POR-15 then put a Dynamat type insulation down.

My apologies for hijacking another thread with my plea for sympathy regarding water in the driver side floors from a long drive through bad rain. This has prompted me to pull the carpets and insulation off both driver and passenger sides to check condition of floors, then dry and treat...

Thanks Steve. I’ll go have a look at that other thread. M.
 
In restoring my E24 I decided to stay as original. Put down new tar paper in the engine compartment to begin with. In the cab I did the same. The foam came out of the cabin intact in spots and deteriorated in others. I glued down what was left of it and then rebuilt the missing sections with new foam of the same thickness and then covered or bonded everything together with a thin sheet of neoprene overlay which gave me a very original look. I am not saying there isn' a better way to go , it was just I wanted to maintain that look. I also built my firewall blanket the same way but instead of foam laminated it out of two different thicknesses of neoprene and it is very hard to distinguish it from an original factory blanket. I sprayed on upholstery grade contact cement for the bonding agent
 
I used this ( ice and water shield) to keep my original foam/rubber in my E3 intact. Self sticking, thin, holds it all together. On the E9, too far gone so dynamat.
