Here's my '64 NewYorker, which I rolled with semi-gloss black paint and a rounded roller over a year ago. I used a little brush first to paint the areas the roller can't come. I've covered each section only 2 times, cause I used an old can of paint and I wasn't sure I could get a new can of the same stuff again these days. The paint I used however was regular housepaint. Nothing special.
The car is a little dusty though, but I'm happy as can be with the way it turned out.
