After reading about these products I would like some feedback from users of Zaino's products. What products did you use? It seems like they are a lot of work to put on but if they last for a long time they may be worth the effort and expense. I have to wash my truck frequently (salt and slush in winter, bugs,dirt and mud in summer) . The waxes I have been using do not seem to last very long. Also have any of you tried their leather products?
