Here check this out.
The original style paint is not available any more.
Are you wanting a semi-gloss or a flat black?
If you went with semi-gloss. I would use Spies Hecker Rallye Matte Black.
Part number FP1004
It is a urethane that is semi-gloss right out of the can.
You do not have to wrestle with gloss flatners or anything like that.
If you use a semigloss, it will look newer-longer than a flat black. Just dont wax any flat or semi-gloss exterior paints, or it will eventually get more glossy, and the wax will show.
Hope this helps.
