Re: Chrome rim repairs
South East sands down the entire edge around the rim to make it look even. Thereafter buffs the edge to shine it up. The issue is that the aluminium is exposed and after a while (1-2months) the surface becomes dull again. The chrome surface that comes on your rim is actually either chromed plated or lacquered polished aluminium.
IMHO, if you got a minor rash, get a fine needle file to remove the rough edges and use some 1500grit sandpaper to wet sand the area. To finish off, apply lacquer to the area with a brush. Use the Pylox can and spray into the cover.
good luck
