[Healeys] Tire Black

We can recommend No Touch Tire Care from Permantex. The directions imply that you just spray on and let it dry.  The trick to get the new tire look is to let the foam set on the tire for a minute or so and then wipe it off with a shop rag. The foam lifts the brown tire oxidation and grime and rubbing it down removes the extra gloss.  Provides a clean slightly more than matte finish. It will stain the concrete driveway/garage floor so lay down a bit of protection before spraying.  Cost varies on where you buy it.
