How do you not chip painted bumpers with bolts?

Going to put on painted bumpers soon. The ones I took off were crazy chipped all around every bumper bolt...what are you guys doing to keep your bolts from messing up your painted or powder coated bumpers?

Im thinking like little rubber o rings or hose gaskets or something?

Mine look perfect. Of course, I just put 'em on today.

But the '72 had painted bumpers, too. And I never had any cracking or chipping where the bumper bolts met the bumper.

I think probably the reason...or the way to go...is to make sure the carriage bolts fits squarely (of course), you adjust the brackets so
and the head of the bolt takes even pressure all the way around. In other words, lays flat as you tighten it.

Possibly, I've had good luck because I put the bumpers on both times when the paint and clear coats were both dry...
...but not fully "cured". But I'm not sure about that.

I do know that I didn't torque them down with an air hammer. Don't know how many pounds. Generous torque, not 200ftlbs.
I saved the serious torque for bolts that connect the brackets to the frame.

My solution was mount and adjust fit, weld them in, grind heads off and prep the bumper and then paint it.

Do not use air tools to install. Use a hand ratchet and go very slowly

I would think that if they are properly prepped and painted, they won't chip just putting them on...with hand tools anyway.

I bet most chips happen when the bumper bumps something.
