Has anyone used ceramic coatings to cut the temperatures under the bonnet?

 

but since I had that installed at the same time as I had my tune done (and some other work) and since I neither had, nor have any way to measure temps in a way that allowed me to compare, I don't know whether it helped or not.

I'm pretty happy with the car as it runs now, though I want a Jesus Head and some other goodies in about 10-15,000 miles (depending on what if anything else goes pop in the meantime, and how much money I have available.

The header has an OEM CAT and is hooked up to a Milltek cat-back. Sweet sound!!

I have been recently focusing on interior bits: nav, XM, blue-tooth, armrests, and soon-to-come wet okole seat covers and rear speaker upgrade and MAYBE a small sub-woofer. Poor house, here I come!!

 

it would be interesting to test those performance and temperature claims ...I wonder if Jan has ever...
