Adam is looking for a ceramic sealant, not an insulator. BTW, I thought you were done with lowers??? :P

Regarding a high-temp ceramic heat management coating I've had okay luck with Jet Hot, but their coatings will discolor with extreme exhaust heat and they are not a good thermal barrier. The only one I've found that holds up extremely well and acts a functional thermal barrier is Swain Tech. It's not real pretty stuff (a thick white rough coating), but it's extremely functional and durable. I trashed everybody else's coating that I tried on the headers of my TT Viper. When a customer of mine (NASA) suggested I try Swain Tech I was skeptical, but to this day that's the only coating I've found that still pretty much looks like it did the day it was done. Not to mention the under-hood temps dropped significantly. You can even brush your hand against the headers and not get burnt... this stuff is the real deal!

Edit: The ST coating you want to use on exhaust is their "White Lightning (TBC-EX)"

Wilson polishes the lowers and then clear coats them. I've seen so great result lasts yrs.

This one came out fine, worked well and several dyno pulls, street miles, and 1/4 passes later it never flaked. Just turned a brownish color. The parts that weren't subjected to the worst abuse held color fine.

Wilson is using some sort of clear ceramic coating (that looks like regular clear coat) and feels slick like graphite. This is from a write up I found:

"Once the drives are refined, Wilson Custom Marine offers a ceramic coating that will keep the drive finish clean for two years for $250 per drive."

302 you are correct about the coating is clear and really slippery plus when finished it is shiny.. I asked techline coatings and they said its not their product. I would nt be surprise if this coating comes from England.

Don't worry it's not a "Lower" that I would be coating

i had it done in aurora il.i don,t remember the name of the place but dan [icdedppl] told me about it.pm him and he can fill you in.

For anybody interested, it is a "Ceramic Polymer Nanotechnology" process.....

Mike, those guys over there split up, the guy who used to do the Durafortress is gone and no one knows where he went. They didn`t do one of my tabs so now I have one thats shiny and teh other turns dull in a weekend... looking into another coating ..

Don't know what the ceramic coating is that Wilson sprays, but it still looks new after two seasons of running. Just wash with mild soap and dry.
