There’s a long list of benefits that come from jamming a big engine into a little car: the speed, the sound, the terrified wife, and so on. But a big drawback is unwanted heat and noise. To address this issue in our Project Thunderbolt Miata, I ordered up LizardSkin products from Summit Racing. LizardSkin is an environmentally friendly, spray-on coating that provides seamless thermal insulation and protection against unwanted noise. It also helps protect the steel from moisture and corrosion.

We used LizardSkin’s Sound Control and Ceramic Insulation products and applied them with the company’s SuperPro spray gun kit. After going through the whole process start to finish, I highly recommend this product. I know the results will make it time well spent.

This is the LizardSkin Trifecta—Sound Control Insulation (LIZ-51528), Ceramic Insulation (LIZ-50105), and Super Pro Application Kit (LIZ-50125).

Some prep work was needed before we sprayed on ‘The Skin.’ Up first was protective seam sealer.

After covering the car with masking tape and plastic drop cloths to protect it from overspray, we shot some primer on areas that needed it.

The Super Pro Application Kit comes with a mixing paddle that attaches to an electric drill to mix the LizardSkin to a milkshake-like consistency. Yummy!

After adjusting the Super Pro gun’s spray volume and pattern, we sprayed on the LizardSkin in an even, sweeping motion.

This is the result after a second coat of LizardSkin Sound Control. It takes about an hour for it to dry between coats. You will need to wait 24 hours before applying LizardSkin Ceramic insulation.

The interior after applying the LizardSkin Ceramic Insulation. It looks very professional and makes the sheetmetal feel and sound extremely solid. I can’t wait to try it out on the road.

After I finished applying the LizardSkin, I painted the firewall area of the engine bay. It’s now officially time to start reassembly!
