F27 Posted April 26, 2009 Share Posted April 26, 2009 I bought a G5 case a while back on the net and it was used, had all the guts taken out of it but was in excellent condition, not a scratch or blemish anywhere. Anyway I have been working on converting it for ATX use (the purist approach) for a while and then I went on holiday. When I came back to my horror areas on the inside of the case has oxidized, there is a mix of pitting, hazing and smudging where someone has put thier hands when removing the inside parts (not me!). Needless to say im really damn annoyed because the point was to run it with a window. It was not like this when I left, no visible signs that this was going to happen. I thought (obviously wrongly) that because the case was entirely treated aluminium this wouldnt happen, now I find out only the outside of the case is treated for oxidsation and the inside parts are just bare aluminium. Having said that I have never seen bare aluminium do this in all my life. I was wondering if anyone knows how I can remove these marks, ive seen compounds which will only work with smooth mirror aluminium but I want it to go back to the matt sand blasted look. I was thinking of getting some aluminium coloured spray paint and lightly dusting the affected areas but it might end up looking worse. I really need some help with this because so far its only in select areas such as round the air baffles rim and on the drive shelf.

apple apple Posted May 3, 2009 Share Posted May 3, 2009 Never worked on a mac case before, but if it's just bare aluminum it should be an easy fix. It's oxidation, not rust, and you should be able to remove it with a polishing compound and a dremel. I'm not sure that it's necessary, but you could always mask off the exterior of the case and hit the inside with a clear coat when done.

F27 Posted June 20, 2009 Author Share Posted June 20, 2009 Sorry about the late reply, thanks for the response apple apple. The inside of the case in un-treated bare aluminium which has started pitting in a few areas. When you say compound I dont really know what to use as it might mess up the areas next to it which are fine. I used some light sandpaper which seemed ok but it left visible areas of smudging. If anyone else has some input I would really appreciate it. Thanks.

apple apple Posted June 22, 2009 Share Posted June 22, 2009 You could try working your way up from whatever grit sandpaper you used, up to 2000 grit.
