What's on your engine compartment walls?

I finally ripped out the crappy diamond tuff leatherette that was glued to the walls of my engine compartment. Now I need something to cover it with. I'm thinking of thin, black soundboard or just sanding down the fiberglass and painting it black. I noticed that the wall behind the shrould curves out as it comes up to the hinges for the engine bay cover. Is this common for all speedsters or just older IMs? This makes it hard to attach anything that is thick.

Ron, I just ordered a replacement set from Henry @ IM.
The original set was perforated, black vinyl, with a foam sound insulation backing.

Ron, I'm building what I think is a 8-10 year old CMC body. No way that I know of to identify the make. The firewall is basically flat. I just picked up, trimmed and fitted 1/16 inch polished aluminum diamond-plate. I cleaned the surface and sprayed it with a clear urethane to keep it from getting dull. Fits great, looks great, and is easy to work with. It might look a little too glitzy for a traditionalist. But hey I'm painting the beast bright yellow anyway....I've learned that when I only have 1/4 inch fiberglas between me and eternity,,,,,I do...want everyone to see me coming, and get out of my way!!!!!!!!

This may sound kind of weird, but I like the look of the 'spray on bed liner'...just not the rough surface for traction. Kind of a spackle-type paint.

Ron: I recently finished a CMC speedster and used shop floor padded floormat material on the engine compartment firewall. You can get it from Home Depot or a DIY. It is about 1/4" thick and comes on a long roll at a 6 foot width - they just cut off what you want. It is easily cut and trimmed with a utility knife and you can glue it on with "3M 90" upholstery ADHISIVE (use lots on both the pad and the fiberglass). Not only does it look really sharp, but it provides a lot of sound deadening back there - now, all I get is the exhaust note! I also used this padding behind the rear seat in the empty space between the seat back and firewall, and under the floor mats, but it was a bit thick for the (front) trunk, where I used a slightly thinner carpet pad.

I jused " Brown Bread". It is a rubber viscous material with aluminum foil backing. The foil is what you see. It stick to the side of the interior and is a sound deadening and heat dissapaiting material... Looks great and all of the seams you can cover with standard foil duct tape.

Brian, what is that stuff?, where do you get it? Is it cheep oe spensive???

I'm looking for a sound deadner/insulation with pre-adhesive, and I can't find it anywhere!!
