how long for paint to cure on car
3 Answers. The paint on a newly painted vehicle is dry winthin an hour or so, so no need to worry about insects or debris after that time. The paint, although dry, does require a significantly longer time to cure however. Do not wash or wax the vehicle for at least 30 days. If the vehicle was painted professionally, the shop will have buffed the vehicle with a compound that will protect the finish for quite some time.
