We used the "Wally World" brand last year, it's what we had and my son won the pack derby. This year I tested the Pledge "Clean" vs "Favor" brand, both made by the same company. There was a slight advantage to usind the "Favor" brand, and we went with it. His car again won the Pack derby, as well as the Open race (5 additonal runs, I believe about 14 total between the pack & open race) - with no re-prep of the graphite between the races. Spray it on, shake off the excess after about 15-30 seconds, and let it set in a clean space/container for 6+ hours(what we did, I'm an engineer & can't stand the "overnight" stuff - it's completely different in SO many ways) then hand polish with a Selvt cloth. Burnish the graphite into the wheel bore & axle and make sure to keep the wheel/axle pair together(and burnish directon is the same as the direction the pair will be used on the car). Then go win some races!
