I had to pull my clutch out of the Roadrunner. While I had it out I had the flywheel resurfaced. Well that nice machined metal will develop flash rust in hours. So I usually coat it with motor oil. But that is messy so I thaught I would wax it. It has been 3 days and all is well. WHen I put the flywheel/Clutch back in tonight I will just wipe it down with "Prepsol".I also coated my new Centerforce PP with S100 also.
