My front bumper was was damaged in a minor fender bender… I decided to have the whole front end done to fix the damage + stone chips. The repair guy said something about a clearcoat finish so I shouldn’t need to wax the front end of the car for a year…

Is it safe for me to go to a carwash? Should I avoid carwashes altoghether? Or just avoid the ultimate wash? Why should I avoid waxing the front end? Any info would be great.
