I have a black '04 Xterra to detail next week. I've inspected the vehicle and noticed all the black plastic trim/cladding, especially the grille, looks kinda weathered. The grille is kinda splotchy in appearance and the black cladding just looks dull and lifeless. What type of product can I use on this stuff that I can buy locally? I already have AIO and VM which I might try since they both remove oxidation and are safe on trim. The customer (my co-worker) wants me to try to revive the trim, but I have never dealt with this much plastic trim before. Any suggestions??
