Hefty sanding or shot blasting before painting?

Chris,

I think the secret is getting the chrome off

Perhaps a saline? solution with the wiper arms in, a 9V battery connected to the arms, so current flows out of arms, may remove chrome?

Sort of antichroming.

Anyone else think this'll work?

Frost do a phosphate kit that coats stuff with a black finish. It's an electolytic process like chroming but I think you have to buy it so it might not be suitable. You don't want to mess with the Antichrome, I saw the Exorcist and he is evil incarnate.

My previous post was,of course, complete bull.

Done a google search and came up with:

Possibly the best:

Removing Chrome Plating

Q. What is the easiest way to remove chrome or can you let me know where to purchase a chemical to do this with as my supplier stopped selling the stripper that I used.

A. Sodium hydroxide at 8-12 oz/gal (w/v) works well for electrostripping chromium from carbon steel substrates. The bath can be operated at ambient temperature or higher, at a current density of 0.25 - 1.0 amp/sq.in. The fumes evolved are toxic and must be evacuated and scrubbed. The bath starts out as a simple solution of caustic soda but acquires an increasing component of a hexavalent chromium compound as the metallic chromium is electrostripped from the workpieces. The spent solution is hazardous waste and must be properly disposed.

The Hippy is right - you can do it by sanding hard - I have paitned what was a chrome grille on my car. On the second attempt I sanded very thoroughly and the paint has stuck well now - it's a case of getting something for the paint to hold on to.

I was told to use acid etch primer but I couldn't find a source for the small amount I needed so I used elbow grease instead!

where can i get some elbow grease? do halfords sell it?

yeah next to the long weights

I still cant accept that you cant buy black arms to fit.............most are nowadays!

mr useful

What donor did they come off of??

Ian

Thanks for the answers guys(apart from Steve, obviously)

They're shortened MG Midget ones, the early type with the positive screw fixing rather than the "clip and hope" later type.

I think I'll try sanding them as me and chemicals could be lethal!

Thanks again

Chris

chris - try wearing really dark sunglasses!

Then they will look a little bit black.

Wow - all these great ideas!

Just let me know Chris, I have loads more like that

yeah, Thanks Steve.

If you've got a week to spare, you could try soaking them in coke. (!)

Don't know if it would work, but I remember an 'experiment' we did in science at high school where we dissolved a coin in coke.

Mind you that was a few years ago.

ca****m do black wiper blade arms its on there web site.

Would they still be black once they'd stuck them up their a*se?

Can't see that being a"Locost" solution!

Cheers
