Extreme Green originally was developed for Midwest tracks and is a very aggressive track side softener that works on tracks that contains moisture or is extremely dry slick. This prep is different than any other prep on the market as its designed with an extremely aggressive oil but it does not sit on the tire for long or fill the tire up so rapid coats can be applied in a quick amount of time if needed 

General Use:

EG is best used at the track and does not have a defined durometer range but it can be used on all brands of tires and is used to create and large amount of grip and will quickly soften the outer layer of the tire.

Weekly - 

Not advised

Trackside:

Use sparingly, this is a very aggressive prep and can be wiped on wet right before you go out or allowed to dry with multiple coats added for even more bite. Be carful when using with heat as it can lock a tire down very quickly and can be used over any of the other PTS products.
