Getting the Chrome Off ...

I picked up a pedestal from one of our members a couple of weeks ago and have it pretty much all in pieces now. I figure on wet sanding the painted areas before I take them into a shop and have them powder coated.

However, the shift unit is chromed and is pitted a good deal. How can I get the chrome off without messing up the Aluminum component? Any good ideas?

There is no guarantee of no damage even if you pay the re-chromers to strip the old stuff off.
The only guarantee of gentle treatment is if you take a dremmel motor tool, and do it yourself.
I am speaking from lots of re-chroming experience on classic cars.

Re: Getting the chrome off...

A Dremmel might leave marks making it obvious it was ground out. I would try a bench mounted wire wheel which won't give you gouge marks. I would not try a drill mounted wire wheel where you do not have as much control. Or ask the chromers if they can remove the old chrome.

Re: Getting the chrome off...

Using a plain steel wire brush leaves minute pieces of steel in the part being brushed. Makes for a wonderful rusty mess until all the little particles all corrode away. Might be able to passivate it with acid if you do use a ferrous wire brush.

Best thing is to have the plater galvanically remove the chrome then buff out the pitting before rechroming. Cheapest is just to live with it.

I'll never have anything powder coated again. Once corrosion begins under it, it comes off in large blotches. When the corrosion starts, it's never ending till all the powder coat is gone. Best to properly prepare the surface and paint using the paint suppliers aluminum paint process.

And I'd use a sand blaster. I blasted all the chrome off a bronze helm wheel with good results. If the chrome is already bubbling then it'll come off fairly EZ.

Also had some aluminum winches that I blasted a ceramic coating off with good results.

Re: Getting the chrome off...

I think maybe a Glass bead Blaster might be the way to go, a bunch less abasive then sand ! Ive used it for taking chrome off in the past (when I had things like that availble) It works a little better, and less chance of messing up!! Bob and Connie

At any rate,,i am suggesting doing as much of the prep work as you can before sending it to be final prepped and re-chromed.

Re: Getting the Chrome Off ...

It occurs to me that I have a bucket of 220grit aluminum oxide sand blasting medium. I'll give that a try first on the inside of the housing and see what the result is. I tried using that 220 to clean up some tools and recollect that the finish was satiny with no deep pitting.

I was posting more to see if the chemical means were worth a try but perhaps the sandblasting is a better idea.

thanks for the discussion.
