My car has been vinyled for almost 3 years I think.
1. Once you damage the vinyl in any way, it's permanent you aren't buffing out scratches from a thin printed sticker
2. When it chips if chips white and generally stays white, because the generic color was white before it's color was added
3. Vinyl holds up great in poor weather, and it protects the car underneath, and I've not tested this but it makes sense that in an accident it would hold the broken pieces together for easy collection
4. Vinyl can be more regularly cleaned in similar fashion of paint, however someone said they wax theres, and that's bad for it you can damage vinyl doing that, best to use a vinyl shiner or an after wax spray.
5. Application for too long can damage the clear coat upon removal
1. It's fun and easily diy
2. It's inexpensive you guys quoting 500 are about 200 too high
3. If you tear or rip or scratch dip you can semi-easily fix it
4. You get tired you rip it off
5. It can get stuck in door jams or rubber seals in a very annoying possibly non removable fashion.
6. IMO matte finish dip is horrific and you should gloss it when done
I've done both to cars, hope this helps instead of the hateraide conversation taking place which isn't really any good knowledge.
