Paint or vinyl

[Kamakazi]

Just looking for some personal oppinions.  I am looking to either airbrush my plastic, or put on some good vinyl stickers.  What would you do and why.  It would really help to have the opinions of people with painted plastics to testify for the strength and durability of the paintied plastics.  I am a bit leary of cracking, but im sure if its done right it shouldnt crack
