Because Phoroptors hold their value so well, many doctors have them re-painted when they become scratched or marred. Below are some pictures of an instrument that was about the worst we ever had to do. It was originally green, then sprayed black.
This phoroptor's finish was so bad, we had to strip the old paint off with a sandblaster before it could be re-painted. The picture to the left is the inside of the sphere housing. The picture to the right shows the cylinder housing before all paint had been removed. The center picture shows all the castings after blasting, before they are primed and painted.
