When I drill on my boat. Put tape over the area. I also use a very sharp drill, many like to use tapered drills that expand the hole as you drill, others start with small pilot holes and then graduate to larger drills. Best is to practice on a gelcoated fiberglass panel first before you try it on your car. Also make sure the selftapers going into the holes do not crack the glass. Again best to practice on a panel before the car.

Have fun
