get it buffed and polished. i worked as a detailer for 3 years and now i work in a body shop buffing freshly painted cars that have been wetsanded with 1500 then 2000 grit paper. you can wax and hand compound all you want but nothing beats a highspeed buffer. but if you dont know how to use one leave it to a proffesional!!!!!!
both mustangs ive owned are black and so is my s-10, i wanted a black f350 but was limited in options at the time of purchase, but im going to paint it.
waxing and hand compounds are good, but i would say take it to a good detail shop and pony up the cash to have it clay barred and polished. at least once a year. i used to wax my old mustang once a week and polish it every few months, i dont have the time like that anymore but i still do it alot.
sorry if i seem enthusiastic about this topic but it pretty much has been my life since i got my first job lol. and i LOVE black cars/trucks!
also clay barring before waxing is key for a smooth finish. heres a trick to REALY feel your paint. lightly rub it with your fingers, feels smooth? put your fingers in a celophane (sp?) wrapper from a pack of ciggarets. now feel your paint the same way. ICK! lol. the celophane allows you to feel every imperfection in the paint that your skin conforms too. then claybar the car and do it again. nice and smooth with the celophane.
