I had my rear bumper and rear 1/4 panel repainted about 3 weeks ago. Anyways, the guy at the bodyshop says not to wax the car for 2 months because the paint has to cure. I'm wondering is it ok to wash the car? Because it rained today and my car's all dirty now, I'm just wondering if it's alright to use car wash detergent on the paint. Thanks.
