My local hardware store had the Krylon Fusion on sale today, for $3.99, so I bought two. Color is exaclty the same as my plastic lawn furniture.
It didn't go on smoothly, though. Lots of areas that look like thicker masses of paint, and a few drips. Maybe if you did a lot of REALLY thin coats, you could get a uniform appearance. I'm not all that concerned, though, 'cause it's outdoors and perfection isn't essential.
