In your case if you want to avoid really scratching your paint and having to have it compounded and polished from the dirt scratching it to hell and back I would just pay someone to wash it and put a GOOD paint sealant on it. Everyone tries to sell waxes because they're "natural" and low harm to the environment with the carnauba approach, but in reality, the man made chemical/polymer based sealants do a MUCH better job and last a heck of a lot longer than your average car wax. Paint sealant just sounds better than wax anyway.
Hi guys, Black is no better to keep clean!!! I wet my car with clear cold water and flush all the dirt off. then wash with chamois cloth and water no soap, dry with chamois, then spray with Mother's Show Time, buy the kit, you get a bottle of spray wax/ cleaner, a soft polishing cloth, and two clay bars. After I do the above I wax and polish with Turtle Wax super wax. You will get a deep wet look shine. Good luck!!!! Your car will be easier to keep clean after the doing above, just spray with water and dry and polish with soft cloth. Dust and pollen can be removed with a Swiffer duster (dry)
