How do you screw into fiberglass/gelcoat without chipping?

Yup, this is the way to do it.

He's drilling 9/16 holes for bolts, not for small self-tapping wood screws.
In my case the drilling itself didn't cause any damage so going in reverse wouldn't help. It's the teeth of the screws lifting the gel before they 'bite' and pull in that was the issue.
