Go to a good shop. Get references. Ask to see work in progress and completed work. If you really want to be carefull, make sure their business license is also up to date.
VW Cabriolet Body Shop Paint Mess
This is all about overspray and dust. We took the Cabriolet to what we thought was a good but economical body shop. Huge mistake. The shop got primer over spray all over the inside of the car. It was horrible.
