I put this Ceramic to the test on a Lexus GX that had been baking in the Florida sun for a few years. My prep was - wash>iron decon>rinse>clay bar>1 step paint correction>ceramic coating. The clear coat still had some faint swirling after the paint correction was completed. I applied this ceramic as directed and it left that Lexus with a mirror like shine. There were no streaks left behind and it actually filled in those areas that had swirl marks! Easy to apply, came with a really fancy microfiber towel and delivered on all of its promises. 10/10 on ease of use, paint protection, shine & hydrophobic finish. I will definitely be keeping this one in my detailing arsenal.
