Manifolds...Paint Or Coat?

..any body tried Calyx?
always wondered how it would hold up and it looks easy
to touch up on the vehicle?
I tried it on a '69 Mach 1 I restored. It looks great and seemed to hold up well although I sold the car a year later so I can't give you long term results. I plan on using it on my 340 soon. One little jar should do quite a few manifolds.
