It was on a Sedan and I did about 5-6 coats I think. I removed the center taillights recently and took the paint off. But the lens cracked somehow. I had to redo it and sand it down it had a lot of scratches on it. I did it a little lighter then it was because you can see the white part now. Would a buffer help after they are all painted with making them look smooth and remove scratches. Any opinions would help me a lot.
