Not knowing what specific plastic you have, this is a shot in the dark...
However, in general, plastics primarily tend to degrade via two major routes
- plasticizer migration and UV exposure. Not sure what you can do to retain
the plasticizer in the material, but you can limit the UV exposure by
painting with a UV blocker. If nothing else, the old standby is aluminum
paint - the aluminum flakes in the paint form a physical barrier to UV rays.
For painting indeterminate varieties of plastic, I've had good results with
Krylon Fusion. It really adheres. As a last resort for a tough problem, I
painted Fusion over 40-year-old Imron (still glossy) on my house shutters 2
years ago, with acrylic latex house paint on top of that. Still perfect.

My question is if I paint the plastic on the replacement globe, will the
paint keep the plastic from drying out and cracking?
