Using Zaino after Mcguiar's Headlight Cleaning Kit use?
I have just just Mcguiar's headlight lens cleaning kit and would like to protect the lens' UV damage.. I am a Zaino user and figure that Zaino All in One followed by Z-2 or Z-5 should protect the lens from UV discoloration. Question is: Do I have to remove the Mcguiar's buffed in paste before applying the Zaino. I would think I should...how?
