Protecting body/paint after drilling....

[Lawbags]

I need to fit some quick release bumper catches and therefore need to drill into the wings.
What's the best way to stop it rusting/corroding once drilled?

Any ideas?

Cheers

Bilt hamber do some great anti corrosion primers I'd get something from them.
