coming from someone who paints every day, i did my baja bug in tremclad white, with a foam roller. and my street beetle is flat black cloverdale speed enamel. i have to fuss over my paint jobs all day at work, when i come home, i just want to enjoy my beetles, not stress over door dings, rock chips and scratches. and i didn't pick the colours till i went to the paint store to buy paint
but hey, thats my opinion. its YOUR car, do what YOU want.
as for black, if you add some silver pearl into it, it will hide scratches and paint swirl like a hot damn. just look at a new dodge or gmc truck
