Mirror Polishing Engine Parts

[K Simmonds]

i will make a how to in the next few weeks with some handy tips...

I'd be very interested to learn what processes you go though New info is always a good thing.

The reason why I condoned using WD40 on bare metal (in particular alloy) is that I'm my experience water can cause oxidation, even when components are exposed for a short time. Where as being an oil (fish based) WD40 does not cause any such thing and IMO acts as a very good lubricant when used liberally. I also find that the wet and dry clogs up less with WD40 than with water. The last set of BBS RM's I refurbished were hand polished using 1200 grit wet and dry with Paraffin as my fluid then hand buffed with Autosol, came up a treat.

other question, how long did you do on that RM's .. the wheels i have shown are 1 saterday work( 6 hours) for 4 wheels including coffeebreak etc.. hand polishing is so 1940 ... use a good polishingmashine.. or a old electricmotor..
with an electrical drill you never get the correct speed for polishing.
and oxidation when you grind with water??? than the structure is to open and you are not grinding good.. polishing is closing the open structure..

When the how to is done can I have a looky to? I have a set of polished Porsche cookie cutter rims that I need to keep on top of. They are fairly shiny anyway but need bringing up again. Any suggestions to get small poc marks out of them and bring them up to mirror finish again?

you can stop at 400/600 and then go to sisal steps ( so you can bring back the 800 till 4000000 sandpaper)
