I haven't had any problem with either of my painted vehicles. Only time will tell. One thing is for sure you can !#$ up the interior doing the job yourself. There's a million things that you could do wrong. If you understand the basics of painting and take your time you will probably minimize MOST of that. I will keep you all up to date on mine. If it starts peeling or looking like !@#$ I will post and warn all. Probably also depends on the envinronment. If you are in like South Texas with an Ungaraged stang you would expect to see more severe abuse on the paint. If you are in the midwest and garage your stang and have tinted windows and use sunshade etc maybe that would minimize?
