keep the stocker

 

its all in the way its prepped for paint. on my truck i was in a hurry to get to drive it and i half assed it and it did chip. if you sand the plastic down smooth, put adhesion promotor on it then prime you will be ok. if you take your time and do it right then all you can do is scratch it. the only way it will crack like that is if there is no adhesion.
