First off, you don't let anyone clay your car for $40 bucks. That clay bar has most likely been used on 40 plus cars and dropped on the ground a dozen times. Sounds like you had a large mexican with some elbow grease. Claying a car shouldn't dent it, but maybe if he slipped eating a carne asada burrito. If you can see the dent , but not feel them...hmmm. I'd call a mobile dent dude and see what he has to say. You might be seeing some fog from the wax, especially having a dark colored car. Give it a good rub down with some maquire quick detailer or re wax it in the shade. Good luck brotha!
