I detail tractor trucks for a living. When I get the trucks, the tanks have already been acidized. I use a 3500 rpm buffer with a blue pad and black rouge. I’m spending a lot of time buffing but the tanks sometimes are still not as bright as I have seen other detailers get them. I do work my way down to the blue rouge but that still doesn’t help. Do I need to spend more time on the buffing or is there a technique to it that I haven’t found? I have also sanded the tanks to a light shine and then started using the black rouge, but that doesn’t make a difference either.
Can you tell me what I’m doing wrong and/or suggest how to get better results?
