Its been a while since I've gone for a full wax, and even after cleaning, you can tell that the paint needs some rejuvenation. I have the Einzsett Metallic polish, but I need something (dare I say) stronger? Should I look to the Einzsett Paint polish or something like such? I have the rest of the Einzsett kit, but I feel I should do all I can to clean up the paintjob before I throw a coat of wax on there and pretend that nothing happened. I gotta do the same on my other car too, which has an even worse lookin' paintjob. Thanks in advance.
