Our local stores didn't have the Rustoleum adhesion promoter so I bought a Krylon product. I did a test spray on a piece of inner tube. Can't get more rubbery than that. I washed it with grease and wax remover, then the adhesion promoter, then Rustoleum primer, then the top color Rustoleum 7754. I wanted to see if there would be a reaction between the promoter and the primer since they were two different manufacturers. Came out great. No crawling or bubbles, and the paint seems really well adhered to the rubber. Now I'll get ready to paint the steering wheel.
