What is ACS sterling coating rated temperature wise? I believe Jet Hot is 1300. BTW, I'm still waiting for pics of the acs gray coating.

 

You can look up techlines coatings. on the site
This is what ASC uses. I also use it.

TECH LINE exhaust system coatings are designed to maintain adhesion at temperatures above the normal operating range of an exhaust system. Unless otherwise indicated temperatures given refer to the base metal temperature that a coating can normally be expected to handle. Depending on the resin system, TECH LINE coatings designed for exhaust systems, can handle base metal temperatures in excess of 2000f. Color change can be expected at lower temperatures with many of the coatings. A color change does not necessarily reflect a failure of the coating, as color stability is secondary to the protective function. Several colors have maintained color stability, to base metal temperatures in excess of 1600f. The use of multiple coats including MCS™ can raise the color stability of all exhaust system coatings.

Ive had problems with jet hot on my personal headers. I have yet to have any headers com eback to me or have any calls with complaints.

 

Hello, We use many diffrent types of coating and coating manufactures, Techlines being one of them. Our silver polished ceramic is rated 1300 degree stable and 1500 deg intermittent,@ this point the integrety of the coating is in jeapordy. We also carry a diffrent coating that is a black ceramic semigloss 2000 degree stable and 2300 int. The grey (we are still trying to figure out how to post pics with our new camera ) is the same rating as the polished silver.Coating comletely through the inside of the headers also helps in the lowering of the overall temp of the coating.
