The Chemical Guys fine grade clay bar is perfect for removing stubborn contamination from your paint. This gentle fine grade clay bar will not leave behind micro-marring, like more aggressive bars tend to do. Simply spray on some quick detailer of your choice and glide the bar across your paint. You'll be amazed at how much contamination the bar picks up and how smooth the paint will feel afterwards. This is the perfect step to do before polishing or putting on a fresh coat of sealant or wax.
