Sean,

Cool Car Ceramic is a one step operation. Product combines a heat barrier with a sound barrier. Lizard Skin is a two step operation, you need both their product for insulation as well as the one for sound proofing. I beleive that the gun for Cool Car is in the same price range as the one for Lizard Skin which is abut $140.00. Price used to be on their website but is not any longer.

Both are excellent products, comes down to personal choice and maybe price, Cool Car might be a less expensive due to the single coat product. Best thin is to check both out.
