G-Wash has been specifically formulated to work in harmony with GTECHNIQs range of coatings. G-Wash produces a high foam content which both breaks the bond between the dirt particles and your vehicles paintwork and lubricates particles thereby enabling the safest possible removal of traffic film. Used in conjunction with GTECHNIQs coatings G-Wash will ensure maximum gloss retention. For light dirt use 2 caps per bucket and 4 caps for heavy dirt.
