Here are the answers to some of the many questions associated with powder coating.
Q: Can you powder coat over body putty?
A: No, it is not a good idea to use body putty, because it is non
conductive and may flake off due to high temperature during baking.
Q: Can you match a specific color?
A: Yes, but it is extremely impractical due to the high cost
involved. Usually a 2-300 lbs of powder has to be ordered to
get a special color.
