Guru Green (actual colour is black) can be used in many ways: alone in cold snow, mixed with other waxes to speed them up, or as a binder. When using as a grip, use in -6°C to -20°C (or colder if you`re brave enough to ski then). It is best used in fresh snow, but will work great in aggressive snow if you use some heat to work it on the base. Apply with cork, or use an iron/heat gun to increase the durability of this as a binder. During my race warm up, I always try to have a tin of this with me in case I need to speed up my kick wax.
