Thanks, Bob, but my problem is sticky white walls. This Revell kit provided the tires with white walls and they were fine when I built the chassis many moons ago. I guess I can remove the white walls with acetone or IPA. If I do, that's it. Black wall city. The wheels are on permanently. Lots of time spent in detailing the wheel covers. I just wonder what will happen if I leave it alone and the stickiness gets worse. 😧
