A specially formulated 2200 degree high temp black made just for turbo components.
Ceramic coating turbo exhaust housing.
I found a local company that told me there is a special turbo coating.
Who is doing the best coating these days.
Abrasive blasting and surface prep.
Keep your turbo exhaust parts looking good and the high temps in with a ceramic coating from stainless header mfg.
Over time this can weaken the cast housing.
Ceramic coating works great.
On turbo components the thermal cycle process can go from glowing red to cool as a cucumber.
I mentioned ceramic and he said absolutely not.
He says it disperses heat and coats at high temp up to 2300f.
A high heat ceramic coating can provide protection keeping the heat internal to the system.
I ve seen some samples.
