Heat Reduction and Sound Deadening Plan

[hdnik]

I wonder if one or all could critique my plan for heat and sound reduction.

After reading numerous threads on both forums, I've come up with a plan, but am still not sure of what success I will have with it. Before I order anything I'd like to take advantage of some experience if I could.

1. My plan is to use Lizard skin on the underside of the floors and inside of firewall. (Both products the 20 mil sound first followed by 20 mil ceramic as per instructions)

2. Then inside, cover floor area, tunnel, inside doors, possibly the roof and waterfall with Fatmat.

3. I will be using The inner foot wells from Kootenai Valley Customs (thanks Tim) so can stuff some insulation in the void as well.

4. Finally put some sort of reflective heat shield above the mufflers, whether that be fabricated aluminum as I have seen done here before, or some aftermarket product ( a suggestion here would be helpful)

Thoughts? Ideas? Suggestions?

Thanks all!

I think that is an excellant plan. I am doing much the same.

Did about the same thing but did the under out side of the panels with rubberized undercoating then black paint inside with fatmat work good , don't know how the Hotrod doors are but on my coupe I filled any hollow areas like the doors (areas were no one can see) with fiberglass insulation it help a lot and gave the doors a more soild sound when you close them.

Just curious. When fastening the floors to the chassis, or any other aluminum for that matter, what is the prevailing wisdom for the type of sealant that should be used. At the build school they just said "silicone", but there are so many differnt tube products available these days. I'd prefer to use something more "automotive" than something from my local home centre.

I've always used the stuff made by GE.

I used the GE silicone suggested in the manual. It has worked great so far.

GE Silicone sealer is not recommended for steel, because it is corrosive. It works OK with aluminum, and it may work over a good paint coating, such as a powder coating, but never, ever use it on uncoated steel.
