I used rustoleum multi-surface satin-black, but before I painted I lightly sanded it with one of those sponge sandpaper blocks then applied "plastic adhesion promoter" I got at autozone (I think it was made by dupont or dupli-color.)
http://www.amazon.com/Duplicolor-Adhesion-Promoter-oz-CP199/dp/B0007UAXJQI have already worn away a small part of the black directly in front of the shift lever as apparently I rub against the shield sometimes when shifting. I can see that i will have to regulary touch it up at that spot.
