Yes Don,
there are many paints available in different colours..
Hi temperature paint from Auto stores..
the only real success I've had is with white hi temp paint..
just put it on very lightly... a few light coats...
Maybe its better heat the paint up, by running the engine after each coat...
I know many people have had bad experiences with high temp paint... and it just peels off....
The best black muffler paint I've ever used is JOHN DEERE brand Muffler paint.. [only in black]
best of luck
Lee
