Rub N Buff
Orcade-Ian:
Might be of some use to some folk:
I did a BMW boxer gearbox (80's) for mate recently - new bearings and lots of careful measurement and shimming. When he brought the box round before the work, it looked like new, so I asked him how it was so good. "I use Rub N Buff paste on the castings and as long as they have been cleaned, they end up like this" was his reply. I bought some (about £10 for a tiny tube from ebay) and tried it on this latest bank of spare carbs for a 400/4. You only use TINY amounts and I applied it with an old toothbrush and buffed it with a rag. It's really a craft type product and Silver leaf was the shade used - lots of other colours available including gold and pewter.
Might be a bit too blingy for purists but looks well enough.
Apparently this gearbox had been done years ago and ridden in all weathers and occasionally hosed down but looked like new castings.

Yes, it's quite impressive and my mate rides this BM in all weathers here in Orkney and just hoses it down. He has a lot of other bikes, Z1's and the likes that you could eat your dinner off! Also a Tractor that went down to a display at Ford in Dagenham a few years ago. You folks ought to come and see some of the stuff up here and in Shetland.
I've tried removing this stuff to see what happens and you can get rid of most of it with thinners and probably petrol - but even if they flood it shouldn't come into contact with the finish and you could always touch it up in places.

That’s impressive stuff! Never heard of it Ian. Have to get some of that for the 750 carbs. Should be back in the land of the living shortly after I get this Lister out of my psyche.

Looks impressive result on the carbs.
It's predominantly carnuaba wax with petroleum distillate (seems like turpentine) with kaolin clay and dye of choice for colour.
Probably the carnuaba and real turpentine that are most expensive components.
