Someone backed into my car in November, and I had it fixed/painted in early December. I asked the Honda body shop manager how long I should wait before waxing the vehicle, and he said 3 months (90 days). My car is a 2016 lunar silver metallic Honda Accord, but I can't imagine that would be much of a factor in terms of how long to wait before waxing. My guess is that's probably pretty universal for nearly all new paint jobs. As for a wash, though, I didn't ask, but I seem to recall him offering up for me to "wait a couple/few weeks" before washing the car....but don't quote me on that.
