Tired of scrubbing rubber, tar, or mud off of your race car? Check out Geddex. Its Burnout Guard can save you hours of post-race cleaning.  Spray it on your fenders, doglegs, quarter panels, and nose and watch the gunk stay off your car. Geddex also makes dial-in window markers that stay visible until you wipe the marks off yourself. Next time you’re at the track, stop scrubbing and start spraying.
