I am sure this has been discussed. I searched on this forum and could not find alot of input. I have people that use XPel or 3M around my area. I am seeing from a Google search that XPEL is a better coating. 1) Is this your guys opinion for the viper? 2) Is it necessary to do the front bumper ? It would seem this is the most prone to get knicked , but mine is not, maybe due to the material? Rockers have some slight rash , so I will do them for sure.
