Honey, I shrunk the ferric oxide

Check this unholy madness, courtesy of Deox-C rust removal powder. These brake discs had been sitting in a shed for many a moon, and were in a state:

Then after a few days in a bath of Deox-C and nothing more than a gentle wipe with kitchen roll:

Before wiping:

After:

And 240 calipers too, but I haven't scrubbed them yet:

Is it just me, or is that a bit

nice:D are those on a 300?

Not yet, but they'll be going on my 360 as soon as my new daily driver passes its MOT, which should be next monday. They're 300mm discs from an M3, bolted to some sort of modified 300 hub. The 240 calipers have spacers in them, about 20mm wider than normal.
The whole lot *just* fits under 15inch wheels. Should stop pretty well...

you could also just have fitted them and brake gently a few times. that way the rust would have cleared from the disc surface just as well...

That's what I would normally have done but the surface was so badly pitted I was worried I might score the brake pads. The rust remover even cleaned inside the vents of the disc too. I've got a rust converter liquid from the same company and I'll be trying that soon.

the product you used, I think I have used this stuff too. is is called Bio-Deruster?

it is advertised as not containing acids or other corrosive ingredients, but that the rust is being eaten away by microbes.

my father uses this on clocks. works great if you do not want to use abrasive methods like sandpaper.

That's where I got it from. It seems pretty expensive, but I only had to use 1Kg to treat 2 discs, 2 calipers, 2 wheel spacers and a pontiac water pump pulley.

Hmmm, I like the look of this stuff! I think the gel would be a very valuable item for any bodywork where you can't submerge it for several hours! I'm also very interested in the corrosion prevention products, as sometimes, the Waxoyl or Dinitrol aren't suitable. I might be spending some time and money on their site soon! Cheers for the link John!

Check out the comparison of their cavity wax versus "UK's leading brand" seriously impressive stuff, in a geeky way
