Is this something that is on the surface of the plastic? Would a sanding down get to plastic that doesn't have this treatment? Or is the plastic rather porous, its doesn't look it?

Sanding may make it worse - silicon and plastic inhibitors are notoriuosly difficult to get rid off - you can drive them deeper into the plastic. A few years ago a car painter mate if mine offered to colour code the bumpers on my then Vauxhall. He took them to a professional spray booth done all the necessary prep and used the special additives but the paint started to flake 6 months later after a few heavy frosts. It's just one of those jobs that there is no gauranteed outcome. I have seen some successes and some failures roughly about 50/50. I have also seen guys spend more than their car was worth on getting their bumpers painted.

Plus flaking paint looks much worse than the standard black or grey.
