Forgot to post this under murphey's law... not saying this always happens, but it did happen to me. A few months ago I got the sterling treatment (higher temp) from Jet Hot on my header.

It lasted all of 10 minutes, and started bubbling up on the dyno...

This was most likely due to bad prep on their part, or oil in the compressor when they sprayed it. Be warned.

 

IIRC they have a warranty against defects... I'd say this would classify as one.

 

yes, had they sent the ups pickup as they promised it could have been fixed under warranty. unfortunately they took their sweet time, days later it never came and i was under the gun time wise with a car in the shop. my time was worth more that the free warranty...no header means no DD, plus shop time.
live and learn.

would up sending it around the corner to a local ceramic shop. they did the high temp external coat, and an extreme temp on the internal overnight.

 

i would definitely contact them about that. that does not seem normal or acceptable at all.

 

read above. I did contact them. No quick resolution. Heard this has happened before.

Warranty is only good if company is responsive and you have time to leave a car lying around while a component gets repaired.
