how to drill painted metal
ok this is probably a really noob question but bear with me, i want to start mounting a few things around my truck but my biggest fear is once i start drilling these holes i'm going to start getting rust like crazy, i live in Canada so we have alot of snow and alot of salt, so does anyone know how to properly drill and protect these holes from corrosion.

POR-15 is for rusted metal unless you treat the metal first with an oxidation agent.
IMHO
Do the masking tape thing for sure.
Finish up the hole.
Get some DuPont Etching Primer, spray the bare metal area, get underneath if you can if not use a Q-tip and spray it then wipe it on the inside as best you can through the hole. Most rust starts on the inside.
Paint with a good DuPont Automotive Paint.
