For some reason my car wheels get filthy within a couple of weeks. Not need to scrub dirty but aluminum gray to black dirty. So after cleaning them a few times within a short period of time with Spray and Rinse(diluted 50%) I got tired of this routine. So after the last wheel bath I decided to use Wheel Sealant. Brilliant move on my part as it has cut down tremendously on the brake dust that so wants to cling to my wheels. I haven't used this cream for a few years and now I know why I like/d it so well.Anyone else's wheels get really dirty in a short period time if so do yourself a favor and get this product.
