can i just take a wirewheel to the bumper and get the stock chrome plating off and then rattle can clear coat it so it doesnt rust up???

Wire wheel won't even touch the chrome, it's much too hard

Now a grinder with a flap wheel, that should get you a surface that is coarse enough to hold paint

i agree with spraybomb. The chrome is way to hard. I had my bumper sandblasted so i can paint it and it still didnt touch the chrome it just dulled it down

I believe you have to have the bumper acid dipped to remove the chrome..

I recently had some stepside gravel guards de-chromed and it had to be done at a chrome shop. But, when I got them back they looked like new metal! I believe they did acid dip them.

its the same process as chroming them /they just reverse the polarity of the current

Not sure why you'd want to do that.... Is it all pitted and rusted?

I'd ask around to see if anyone may want to trade. A lot of old trucks (mine) came without chrome bumpers. I like the painted look (mine again) but it's a lot harder to maintain nick and scratch free. However, they're easier to repair/touch up...

I'll trade ya. It's a 69 and I believe yours is a 72 but you could just cut some holes for your turn signals and your good to go. Course I can understand if you don't wanna mess with it. Just let me know. I'd love to go chrome.

Steven, I have a painted front bumper you can have but if you want to remove the chrome from yours take them to the place on Mt. Vernon.

GREASEMONKEY72 · 02-18-2008, 07:38 AM

thanks for the help guys

its very pitted and rusted and its a little bent up on the bottom in a couple spots by the frame rails and theres a crack in the bottom hole on the left side, plus i like the bare metal and was goin to clear it so i dont have to oil it all the time and the grinding wheel works

fastom - thanks, i appreciate it, but the only thing i have to drive is my truck and its not done yet

Go to the hardware store and purchase some muratic acid (like what they use to clean brick with) and mix it in a strong solution. That should pull the chrome finsih off and leave the zinc coat.

just buy some paintable bumpers, they are not all that much
