Has anyone else noticed how faded the bumper and side trims look after a few months? Despite using the stuff that came in the cleaning pack, the trims look streaky and greying. I clean the car every week and feel I need to do the trim with the spray every two weeks. Surely that's not right. It spoils the look of the car 😢😢😢. I bought some Simonize stuff today so hopefully that'll last longer.
