My wife has a 04 malibu and that car has been a pain to polish and wax since the day we bought it. Most cars you can apply a wax or polish too and it will go on and come off easy. Well, this car not so much. It is black. And whenever I apply anything weather it be a compound, polish or wax I get these marks on it that look like I did'nt remove all the product. Like smears. I can rub and rub and they will not go away, just smear. I was thinking of wet sanding cause maybe it has junk on it, silicone or something like that, that needs to come off first for a good foundation for a shine. There are no low spots, peeling or sun fading. I just think it can look better. I've tried washing with dawn real good then the meguires 3 step system and mostly it looks good but you still see the smear marks. I've also try Zymol after I hit it with 3M perfect-it 2 compound. Anyone have any ideas on the wet sanding idea?
