basically I have a black z, lately considering I was washing it regularly until the weather changed, im noticing swirl marks and light scratches on the paintwork along with some annoying bird c**p stains which I thought polished out, just wondering what the best stuff is to get rid of or atleast cover it, as its beginning to bug me! also wondering what the best products are for the care of the paint etc. ive never really ventured into waxing and that very much and ive never been a great detailer, but with a pricey car I know this time I cant look past it, ive heard meguairs ultimate compound is good for the above but no idea, anything helps, cheers
