I'd say that 30-60 days is a more reasonable time frame after you've gotten body work done. The idea is to allow the new paint to completely "outgas" the solvents and fully cure before you seal it. For new cars, the wait is effectively zero since the car was probably painted months before it hit the showroom at your local stealer.A month or two ago, someone hit my car in a parking lot and I had to get a new skin for the door and have that half of the car re-painted. I've been wanting to wax my car, but a buddy of mine told me that after you get your car re-painted you can't wax it for like 6 months. Is that true?
