The kind of investigation to be conducted (which, for example, can be based on the level of a security clearance needed) will depend on the reason for the investigation. Different kinds of background investigations have different requirements for the scope of the investigative coverage to be obtained.
Instead of trying to measure every inch of masking tape used and every ounce of paint sprayed, auto-body shops charge a flat rate for materials. At a rate of $45 per hour on average, paint materials also contribute to the rising car bumper repair costs.
If your average bodyman makes $15-25/hr, and add materials, you could pay up to $30 to $35 per coin sized dent. This cost of the dent repair is reduced if they fix the entire car. It takes about 12 hours to fully prep & prime a car (without dents). This could cost about $450 with out the paint.
