What I've done is first clean the tires off with some motor spray and wipe clean with towel. Spray WD40 onto the towel and then wipe on the tires till you see that it is slightly wet and let it sit for about 15-20 min. Wipe off any remaining residue/WD40 from the tires and you are ready to run. **If you touch the tires, you will notice that the rubber is very soft and sticky.
I've recently done some more testing comparing it to Paragon's FX2 traction compound and again the WD40 felt much better. Actually the FX2 was very similar to Ground Effects as far as traction. Not sure if there is a difference in the formula they used. Does anyone know?
BTW, if anyone has any knowledge of the difference formulas used for the popular traction compounds out in the market, I'd really appreciate if you can share it with us.
