Well yeah u have plenty of clear coat on them so ur good there. Yeah use 2000 grit sandpaper, wet sand em for a while. Don't worry u won't hurt em. After u wet sand em use meguiars medium cut compound for a couple coats. Then finally use meguiars show car polish for a couple coats. Believe me,it will look fantastic. If u tint tails,you NEED to wet sand and buff em to get that good look. It needs to be done on plastic,metal or anything or else it will look kinda dull. Good luck bro
