Gday guys from Down Under :0) Im starting up a business cleaning and polishing trucks and cars.Does anybody know the best way to clean and polish Aluminum gas tanks and bullbars? (ill be needing to get into nooks and crannies too-the best tools/buffers to fit into small spaces to polish?)Best polisher and polishing wax or liquid polish to use? Ive heard good things about the Porter Cable polishers. Best buffing tools/pads/woolies to connect onto the polisher to do the best job without the swirls? Any help would be great.thanks guys.
