Refinishing Brushbar and Bumper

I need to refinish my brushbar and front bumper. What's the best route? Looks like Powdercoat on the brushbar and paint on the bumper. Powdercoat both?

Also, a mechanic dented the brushbar while it was in his shop. Is there anyway to repair the dent and still have the powdercoating stick? See the picture.

And last, what percent gloss is correct for the brushbar. All help is appreciated.

Are you repainting yourself or taking it off and sending for powder coat?

Reason I ask is what level finishing do you want?. Spot repair or re-paint whole brush bar?

Once rust gets under powder coat it all has to come off and be refinished however you like.

Burn off existing coating, sand blast, then either PC or acid etch prime/paint

The brushbar needs to be blasted and refinsihed. There is more finish coming off than just the dent. It won't kill me to just leave the dent and powdercoat it but wanted to know the options.

For your dent repair, check out a product called Alvin Lab-Metal: (http://www.alvinproducts.com/)

It's a body filler that contains metal and can withstand the heat of powder coating. I used when restoring a motorcycle and was pleased with the results. Just apply and sand to a final finish once dry and then have your part coated.

Good luck!

I know you aren't supposed to weld galvanized metal because release fumes, but why can't you galvanize welded metal?

Briggs, you have crazy eyes. I can't see that. There's a ton of welding on all my stuff that's been dipped and I cannot see any difference between welded and not welded in the zinc.
Well, except for the snotty goobers of weld spatter that give it away....

The powder coat on my push bar had rust underneath in many spots. I removed it all and covered it with some good primer and then flat black rust paint.

IMO - looks better than the powder coat and *way* easier to maintain...
