Polishing...GRRRR. When preparing metal samples for microscopy the polishing was very intensive using progressively finer grades of media down to diamond grades measured in microns. Polish in one direction then grade down and turn the sample 90deg to realign the polish marks ( finer scratches in reality) and repeat at each grade change. Basically creating an even cover of finer scratches at each stage. Imagine aiming for scratch free finish when viewed at 400x mag down the microscope! Luckily they were small samples not large areas. I think DeLoreans were finished with “ mules” to create the final finish of directional texture ( fine scratches in reality and no actual mules were harmed) the result being a brushed effect.
Dirty coffee mug? Make a paste of bicarb and rub it over the dirty areas. Our lab mugs were sparkling clean!
John, I remember reading a while back that Windolene was often used by some owners of ( usually) Caterham types on polished panels.
