first of all......my mags took me about 3 days to do all 4.......and after that my hands were rooted....
some mags have a clear coating on them to keep their shine......this is what mine had on them, although the coating had gone all yellow with age......i finally worked out after trying sandpaper and steelwool that using paint stripper worked.....that stuff is excellent......:D.....then i cut and polished them with a drill buff......and then after that used a product called "bright shine", it comes in a yellow tin and you can get it from supercheap....i wouldnt go past a product called "autosol metal polish" as well.
:D :) :)
