I have not used it but it looks to have great durability (2 year claim). It can be used on paint, glass, and wheels. If you are into claying, polishing, waxing/sealing your car regularly this is not for you. Proper paint prep is a must (decontamination, polishing, etc.). If doing this yourself I would practice on another vehicle first. It all depends on what you want. If your Hellcat is mostly garaged a sealant/wax combination would work. If it is a daily driver and sees a lot of weather a coating may be the way to go. There is a lot of factors to consider.
