I had the same when taking the bonnet to be painted, your man doing the body prep had more to do than he thought!
I've not gotten around to paint yet (get away with it on a white car), plus I've got to take the permagrit wheel to the bonnet a few more times to fit a set of aerocatches and the bonnet vent. One of the plans to get more efficient airflow through the intercooler and radiator ?
