Ceramic Coating for Exhaust

Mornin' all

I'm cinsidering having my headers and collector pipes ceramic coated.

Has anyone done this and are the benefits worth the expense?

Cheers

Reasoning is twofold:
1. Underbonnet temps
2. I want my headers etc to be black.

Hmmmm......

Just a thought, and hopefully someone will comment ref how robust, if you just want them black could they not be chemi-blacked?

Ive seen this done on industrial machine tools and it looked good but dont have experience of it in high temp environments. i seem to think there is another blacking process as well but cant remember the name. One is more robust than the other iirc.

In one of my previous jobs I tested ceramic coatings on offshore drill bit nozzles. I was very impressed indeed. On one sample a piece of aluminium bar, was coated in a white ceramic. The coating was very thin yet even a knife could not make a scratch in the surface and I mean pushing down on the blade! I then got some aluminium nozzles made (coated on the insides) and flowed abrasive mud though them, incredibly after hours of service they withstood the abrasion as well a steel nozzles. So these coatings although sounding rather improbable do sometimes work miracles.

I know John Beardmore (JB on here) has used ceramic coating on his pistons, and I "think" on his Minor's exhaust.

Wrap under the bonnet and BBQ paint from B&Q.

Worked fine on my Avon and black finish was tough and lasted.

Faded a bit, but 2 minutes to spray again.
