I wish I knew what you were talking about. If it's tinted it can be "cleaned" off and ready for a retint. Why you'd strip of your tint to REPLACE it with VHT is BEYOND me. The BEST way to tint tails, is to use clearcoat mixed with a little bit of black and break out the spray gun. VHT is just the cheap alternative and has a bluish-purplish "hue" to it.
