Protectants 1. How often should I use vinyl, rubber or leather protectant on my vehicle?

That depends on where you live. Sun exposure does the most damage to leather and synthetic automotive materials. In high sun exposure conditions, protectants should be used at least once a month on automotive trim surfaces to keep them protected from becoming dull, cracked and dried out. F-21, with Nanotechnology, provides excellent protection from the ravages of Mother Nature. Nanotechnology enhances the protective U.V. and barrier performance properties in F-21 Protectant. Platinum Series Protectant provides the highest shine, and traditional U.V. blockers and protection ingredients for long lasting protection. Otherwise, protectants should be used regularly, anytime automotive plastic, rubber or leather start to lose luster.  more
