Testors rubber. Direct from Dave at PPG. I painted the rings by spraying it through a glass jar/ screw on gas filled canister which is sold at a paint supply or hardware. The spray was good but had to buy a few jars of rubber to fill the jar high enough to reach the draw tube in the jar. I did a search on the web for the testors web site and bought from them through the web site.

If you are thinking of refinishing the black tubes Dave at PPG told me to get a flat black spray bomb from K-mart. I believe dutchboy flat. His specific instructions said be sure not to get the rust prevent flat black just the flat black. I have a can of it someplace along with a couple bottles of rubber I don't need.
