Painting a Holiday Coro singing face

[Donl1150]

I have 3 HC faces that are all of the black coro.  I would like to paint them with appropriate colors so they look more appealing in the daytime.  I have a couple of Gilbert Engineering faces that come pre-painted and they look great during the day.  What type of paint would work best to hold up to the elements?  I live in south Florida so it is basically sun, rain and humidity we deal with here.

Any spray paint made for plastic will work, nothing will last forever if outside in the (UV) sunlight. I've had some coro painted props for about 5 years now and no signs of flaking or chipping even sitting outdoors for the last 2 years.
