Review on Meguiar's G10240 Smooth Surface XL Clay Kit (240g): Ultimate Solution for Flawless Finish by Adam Whittaker

Easy to use; You simply apply the clay to the surface after spraying Quick Detailer onto the paintwork of a washed car and allow the remaining liquid to dry. I do one section at a time and it goes pretty quickly. Then buff it with a microfiber cloth, but as directed in the instructions, a good coat of wax really adds shine. I have used this product on FCA, Honda and Toyota vehicles built between 2012 and 2019 and I see a definite improvement over wax. The paint on these cars is in good condition, so it's hard to tell if it will help rejuvenate a sun damaged or aged finish. Some color issues may be more noticeable after cleaning. Clay can become too saturated with moisture and stick to your fingers. It can also be difficult to get into nooks and crannies as the liquid moves quickly.
