    Hopefully not a 'numpty' question...how do you polish up Aluminum / Aluminium to get that glorious mirror shine ?.

    I'm working on that assumption that it would require a powered polisher of some sort (electric drill / angle grinder with mop attachment !) to save on elbow grease, but what would I use as a polish. Again, I am assuming that I would start off with a course polish of some sort to remove any surface marks and then move onto a fine paste for a finer finish.

    Have any of you guys 'n' gals got, or are actively restoring, a car / bike / plane that you have started from scratch on to polish up so its nice and shiny ? What polishing product did you / do you recommend ?

    Sorry, forgot to say, I'm about ready to start polishing up my '51 cockpit so that gives an idea of the area to be treated.

    Hi Gary,

    I would think about 'wet/flating' the alloy before you start any polishing, this will reduce any imperfections on the alloy.
    You need to get hold of high quality 'wet/dry' paper which has a number higher than 1,200 grade.
    You don't want no lower than 1,200 grade as this will SCRATCH the alloy, always use plenty of soapy water when using 'paper' so it doesn't clog the paper.

    You can get 1,500. 2,000. 2,500. 3,000. 5,000. grade, these are available ONLY at really high quality paint/car/repair shops.

    Audi and Rolls Royce use 3,000 grade paper prier to buffing alloy parts and they get through alot of 'Brasso' in the process. :lol:

    Hair spray might work

    Back in 1959 in the RCAF we used a product that came in cans and was like cotton "waste" that the railroads used only it was impregnated with some kind of polish solution that removed the aluminum oxide. You rubbed it in and then removed it with plain cotton waste.... I recall. :)
