Hello rwwearWell. I don't know. It would depend on how many coats. How much needs to be added?
Exactly! I certainly don't know. I doubt they do. You need to match the moving mass assuming the rest of the kit is "correct" minus the coating. Even if you did it would be trial and error to figure out an application process that will give you an even coat like the original which was also sprayed on. Here is a picture of a 129H cone kit front and back.
Hey Edgewound
Have you ever tried adding mass to an aftermarket kit using a spray on instead of say a mass ring??
