Wintergreen #12 (back in stock)

This is a deep penetrating prep with a strong wintergreen odor. Works good for dirt and asphalt applications.

Apply one to several coats of #12 Wintergreen with a brush or roller allowing to dry between coats. You can also wrap the tires in plastic for a deeper penetration.

A few ounces of #12 inside the tire will also soften the compound when used in a tire rotisserie.

Goat P #5

#5 Goat P (Goat Pee, Goat Piss, Gold, Yellar, ect) provides tons of grip and stays in the tire to drop the durometer considerably. Be careful, as the #5 Goat P will soften the tire enough to cause feathering on a hard track.

Goat P can applied externally in coats with a brush or roller.

Acrysol is an adhesion style prep. When you need that additional bite on a hard track, Acrysol is the answer. This prep seems to work good on marginal tracks when used in conjunction with other preps. Acrysol tends to give other preps further saturation.

Always consult the manufacturer before mixing any tire preps or treatments. Acrysol can applied externally in coats with a brush or roller.

 Tire Tac which is a great adhesion style prep. Can be applied just before you go on the track.

#2 Tire Cleaner - will soften a tire just a bit on it own but really shine in opening the pores of the rubber for a deeper penatration of Goat Pee or Wintergreen. Apply to tire and let dry the follow up with GP or WG as normal.
