You live and learn....
I went to the Knebworth Classic Car show today. Quite busy once the weather had cheered up and lots of interest in the Sportster.
One guy I met was building an E30 based "Special" from scratch - with a hand formed ally body - from the pictures he showed me it looked a bit like the Cabrio. But - to cut a long story short - he gave me a tip for finishing/polishing ally.
Get rid of all the major scratches using 120 grade wet and dry. Then use a Scotch Pad (the sort you use for washing up) with plenty of WD40 as a lubricant. I tried it on a test patch and it works great. It doesn't give you a mirror finish (which I didn't want anyway) - but a semi matt look in which you can just see the marks from the pad if you look close. Anyway I shall have a go with the top bonnets in the next few weeks and I will post up some pictures when it's done.
