drilling hole in bumper

[UWBadgerME]

hello to everyone. i'm a newbie and this is my first out of probably many posts.

i'm planning on drilling two holes in my front bumper to mount PIAA off-road lights. i want to prevent rust from quickly forming on the exposed metal in the holes. any ideas?? or maybe a better idea on mounting the lights?

one of my buddies has some of that spray on bedliner laying around and i was thinking of using that.

The lights are rubber-mounted, no? I wouldn't imagine too much water could get there once you get the lights tightened down, but I could be wrong.

i see you have an 01, if you dont want to drill into your bumper get some light tabs, thats what i have, just use your exisintg bumper bolts, take about 10 minutes to get on (the grille can be a PITA to get off soemtimes)
not really any good pics of them:

I did mine that way and they are fine

Me Too. Either use brackets like for mentioned, or if you drill, don't drill too big and use a rubber washer

You can put clear spray paint on it.

or if you have touch up paint just wipe the inside of the hole with it

just brush touch something on there, I wouldn't go all out and use spray paint. Maybe just get a pint of rustoleum.

Is it a painted bumper or chrome? If it's chrome, put a piece of masking tape down first and drill through that, then either way, just brush touch something (paint) in there.

i just mounted the lights on my bumper this past weekend. i put some rustoleum inside the holes. after that dried, i put two rubber washers on the bolt so they contacted either side of the bumper. hopefully that will work!

Thanks to all who replied! You guys helped alot!
