I have just started a small powder coating (batch oven with a tempture
limit of 500F) business. And have had some interest from customers for
high heat ceramic coatings (inside and outside) on exhaust
manifolds/headers for cars and motorcycles. Where can I find a
vendor(s) for materials and the equipment to apply such coatings at my
shop?
 
Something like this: http://www.jet-hot.com/pages/headercoatings.html
But the above company uses a proprietary technology.   

I would like to use my exsisting 500F oven if posible.

Thanks,
Clint
