People often ask whether or not they need to clay, or how often they need to— The better question to ask is where you park your vehicle when you’re not driving it! For instance, if you park outside, or in an unprotected/unshaded area, you’ll want to reach for a Clay Mitt due to convenience and the aggressiveness of it. If you park in a parking lot or in a parking structure, the Visco Clay Bar will be your tool of choice as there is a decent amount of particles in the air, but large buildings like apartments will guard some of the partial airborne materials. Let’s say you park your vehicle in a garage, or a Sunday cruiser that spends its lifetime in the garage, the Fine Grade Clay bar is your choice.
