Since the fiberglass is pretty rigid (will not bend like PU), it should accept standard fiberglass painting methods and additives- your body shop or paint guy will know what to do.
For the PU splitter, you need to add flex additives to help the paint "bend" with the splitter. It will probably still eventually crack like Flash said, but as long as the hits or dings aren't too aggressive, the flex additive will help prolong the prevention of paint cracking.
I have the PU splitter and it was on my coupe which was set to ROW ride height. I had flex additive added to the paint and I scuffed the splitter on my driveway entrance more than once- not an aggressive hit or anything like that, but the paint on the underside did crack and peel a little (I think the guy I had paint it didn't prep it properly either)...
In my opinion, if your car is set to NA ride height and you are a conscious driver (which I believe most of us are), then you shouldn't really have too much problem with the fiberglass version. If you are the type of driver who frequently tags the front of your car on the parking spot concrete stops, kiss your fiberglass splitter good by.... Pony up and spend the money for the PU version- you'll go through enough fiberglass ones to exceed the cost of one PU splitter over time - easily.
