paint over chrome

[FirstGenZq8]

i have a brand new chrome bumper, but have decided that the chrome look is not what i'm after. any tips on what i should do to this bumper before i get it painted? can you just simply paint over chrome? if i need to remove it, is that something i can DIY to save some money? i will also shave the bumper bolts. using the search feature i came across this good thread for that issue: https://www.pro-touring.com/forum/showthread.php?t=5486&highlight=%22remove+chrome%22.

the bumper in question is below (29-9701):

You need to either sandblast it or the preferreed method would be to take it to a chrome shop and have them dip it to strip the chrome but don't paint over chrome if you want the paint to be on there next month.

I agree with Jason.

Dip it! Under the chrome will be a layer of copper and nickle I believe. Take it to a chrome shop and they will strip it back down to bare metal.

Here's another alternative for you to consider...

PPG has a product in its Matthew's sign paint line that will enable you to paint any type of metal, called Spray Bond Adhesive. Often building signs incorporate copper, aluminum, and other metals. This product allows the painter to lay down a clear to let the character of the metal show through while protecting the metal from the elements. PPG Automotive Refinish teaches how to use the product in their Vibrance custom auto painting classes. I've seen it used to clear over "grinder" designs in bare metal, which produces a really cool effect.

Here's a link to the product tech sheet.

FirstGenZq8, Sand your bumper with 80 grid paper, epoxy prime, and paint. I have done this with great results many times.

I should have added the expoxy will need sanded with finer grit or prime with 2K and sand this with finer grit. I recommend 320 dry grit or finer or 600 wet/dry or finer.

just sandblast it, an industrial blast shop shouldnt charge much, youre going to prime and sand after welding in the bumper bolts anyway, if you leave there a couple of days they should be able to do it while they have the blaster running doing a bigger job.

I have had great results with DP 40 years ago, could be something better now.. Testing it, I had to use a hammer to get the paint to chip on a piece of chrome. Dave

Years ago I painted a chrome rear end cover. I used muratic acid first, scuffed it up and used a zinc chromate rattle can primer. Then used rattle can semi black paint. It worked great, but its not a bumper, I don't know how it would hold up to the road grime and rocks that a bumper sees on day to day driving. I would go with the sandblasting to remove the chrome.

As stated above...
Sand it with 80 grit to cut the chrome. Spray it with Vari-Prime self-etching primer and then shoot on a couple heavy coats of primer surfacer for blocking. Been doing this for years with no problems or issues.

Powder coating would go great on top of chrome.

We painted the bumpers of my 70 Chevelle a few years ago. I used Scotchbrite pads to scuff the chrome down to bare metal and primed. All said and done it took an hour. See photo attached.

As stated above sand blast good primer either DP from PPG or another epoxy primer, scuff it and use a high build primer after, then paint....Powder coat is another way but difficult if you plan to weld and cut to hide the mounting bolts. Powder coat and body fillers don't work well together
