I just removed all the crappy old black insulation that came on my 86 SE and I am looking to replace it with something different, but that also looks good. I am going to look around for something in a spray can, simply for the ease of it, but I am open to anything. I saw that Fieroguru did this, not really my style, but you get the idea  Working on a budget here, being 21 and in school, but any idea is appreciated.

I threw it all away on mine too, just sprayed it matt black. What I have seen on a lot of cars at cruise-in shows and looks pretty good is firewalls and fender wells sprayed with bedliner.

I used Lizard Skin, it's a spray on system for heat and sound, it works.

Do you feel like you get a lot of noise and heat in the cabin? I have a gallon of black Plastidip sitting on my shelf and a sprayer, its tempting...

I never noticed any more heat or noise. Personally, I like an engine sound so to me it wouldnt be a bad thing. I also left off the hood insulation on my SuperBee with a 413/ 4 bbl and dual glass packs...yeah its noisy...

I do not know the exact heat that builds up there, nor the flash point of Plasti Dip. That being said, I would be VERY cautions about using something like PlastiDip so close to the exhaust manifold. I would think that is just asking for trouble. Whatever you use, I would make sure it is made for high heat at the least.

With my old SBC fiero the firewall panel would be about 170 degrees after a summer drive.

If they came out with something that could make the cabin nearly silent I'd be all over it. Noise is my primary complaint about the car. ------------------  [This message has been edited by RACE (edited 03-08-2014).]

Strip out the entire interior and install sound deadining insulation and there would be a significant difference. ------------------

When I installed my new carpet kit I left the old carpet in and installed the new over top of it at somebody's suggestion. It worked well but it's not as quiet as I'd like yet. I should go back to my build thread and see who recommended that.

Doesn't anyone make anything black? I do not like the foil look at all. ------------------

I ended up with an extra layer of carpet over the back panel in the cab and it reduced interior noise quite a bit.
