+1I've never done a complete exhaust..I'm sure any hi temp paint would be the way to go....Prep is always the key to getting paint to hold..A good scratch so the paint can bite into, But still bury under the paint. And clean the snot out of it with a solvent..Laquer thinner, paint prep, etc.
I did this on my stocker about 3 years back, still looks like new...I used "one shot" sign enamel.
Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin." The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.you could just get it powder coated right? That is like glass that binds to the metal. It comes in a million different colors too.
