[DeTomaso] Exhaust coating questions?

[Asa Jay Laughton]

I had mine for the Mach I done by Jet-Hot Coatings.  At the time there  
were only a couple houses that did this stuff.  Now there are plenty.

The headers should be as clean as possible down to bare metal.  The  
process as I understand it requires bare metal.  Some places will  
blast them for you at additional cost.  They will most likely not do  
much to the inside except a cursory blast; I can't see them doing a  
great job on the inside.  You may do better taking them to a local  
place that can blast them for you, to your satisfaction.

The shop that does the coating (yes, I recommend ceramic and not just  
plain powder coating), will coat both the inside and the outside.  The  
inside may not be as thorough and certainly won't be shiny.  They  
can't really get in there to polish it but it will be at least  
partially coated.

I had mine done in a light silver-gray.  They looked kind of like a  
satin finish chrome (if you can imagine such a thing).  They retained  
the look without any spotting, fingerprinting or blueing for years.   
Only in the last few years have they started to get a little surface  
pitting, but I blame that on the owner parking it outside all the time.

I would do it all again I like the coating that much.
