Though just have to add that with clear coat it will sometimes turn yellow, oxidize, and peel over time. Or at least that has happened with the customer cars that I've worked on lol. It's just extra work for me to sand off the old clear too. Usually if the oxidation is bad I start with 400>600>800>1000>1200>1500>2000>3000 in that order all wet with soapy water. Then buff with compound and polish. If it's not that bad then start with 800 grit and move up. It takes FOREVER to do, but the outcome is great and lasts for a very long time! It's like having a new headlight without the high dealership cost!
