So my paint is knackered, first of all its red, which so the internet tells me is known to be the first to fade. but anyway basically my paint is starting to get an almost matte finish and there is water marks on my bonnet, but do i clay bar it then go over with a red paint scpecific polish then wax orrrr what i've done a search but theres so many different ways and was just wondering has a decision been made on the best process for restoring paint ?
