Engine bay firewall heat shields

[jcraigau]

Hi Guys,

I'm currently lining my engine bay in aluminium and wanted to know what others have done to stop heat soak coming into the footwells and cabin.

I've found the following;
for inside the cabin Kool Mat thermal heat shield, aircraft insulation, fireproof material, race car insulation, firewall
for inside the engine bay Zero Clearance is a premium quality peel and stick heat shield material, under body engine bay heat

Other options I've considered;
- Spray-On Insulation - Automotive Insulation Coatings | LizardSkin
- Carbon Fiber Heat Shield | Heatshield Products
- Dynamat.com | Dynaliner for Automotive Use

I've heard everything from plate the engine bay then apply the heat protection.
Place the protection against the fibreglass firewall and then plate it with aluminium
Just put the protection straight onto the fibreglass and forget the plating
Just go with aluminium and forget the protection.

Some conflicting information, so keen to hear what others have done, what they learnt, and what would they do if they had to do it again.

Thanks,
JC
