Should have been a tutorial Derek!
It was remarkably easy actually. Of course the pipes have only done a couple of thousand miles so hadn't deteriorated too badly but then the finish from new wasn't that great either and they had definitely taken on a brown hue with some mottled bits.
At the last Lanark Show I bought an all round polishing kit from
thepolishingshop.co.uk. I'd polished a couple of alloy items and a brass pepper mill but had never got round to using it in anger.
I started off with a sisal wheel on the drill and the grey heavy cutting compound.
I just whizzed all over the surface until it had a uniform silvery finish.
I followed this with a white close stitched mop and green medium cutting compound.
After this treatment it was looking very nice and shiny.
Finally I used the general finishing compound and the loose G quality cloth which brought the final polish up a treat looking more like chrome plate.
I had to run the drill a good bit slower to stop this mop from flying apart. It's obviously not designed for high speed.
The whole job took me about 2 1/2 hours. 30 min to take the exhaust off, about 90 min to polish the pipes and about 45 min to refit them.
There are polishing compounds specifically for stainless steels which might have been even better but the kit I got was well worth the tenner and there is plenty left to do another 2 or 3 exhausts, and it works for titanium too.
