Touch Up Zone LLC uses OEM (original equipment manufacture) approved coatings. All colors are exactly mixed in accordance with the “standard” OEM formulation. There are several factors that may cause the vehicle to “drift” away from the OEM standard color standard (see Tech Tips section “Color Matching Challenges”). Because of the many factors that contribute to color variations from the OEM standard Touch Up Zone LLC does not guarantee a panel to panel color match. Colors mixed are in most cases “blendable” matches to the OEM color standard.
