I recently had my car headliner put in. I think the guys did an awesome job. However I did notice on most of the interior panels they do have some tool marks from prying on them with pry tools to remove them. There are also 2 or 3 very small little knicks around one of my vents that arent really that noticable. I plan on replacing the stuff that is blemished only because it is so cheap and I am that anal. So my question is even with a professional doing this kind of stuff, is it unavoidable to have these things happen? I spoke with the installer who has been doing it for 35 years and he told me that sometimes you have to take into consideration that the plastic is designed to break away in a crash and not be taken off for any other reason, so it is a bit softer and more delicate than older stuff, and that the options are usually live with that fact or go the next step and consider replacing things like that.
