For those that have used the unibit or other devices to drill through the external paint coat, two questions:
- What is the best way to prevent splintering / cracking of the surface as the drill bit cuts through? I'm guessing a strip of duct or electrical tape.
- For those that did this some time ago, have you had any issues with rust around the new hole?
I was wondering after I drilled the hole if I should touch it up with some high temp grill or engine block paint?
Thanks.
