    So all of your trucks have aluminum dump bodies and they are just not as shiny and nice as new ones I see people driving around with. Without spending the money to have someone come and sand blast (or what ever they use) is there a buffing/polishing compound that we could do on our own?

    All depends on how bad you let it get, it its chalky or pitted you will have to sand then polish. You will know pretty quick if you just try and polish if it needs to be sanded

    The chemical is sometimes referred to as an etching, or as an etching wash. It helps to remove the aluminum oxide which is a lot of what the discolouration is, and then allows you to polish the softer aluminum.

    I've been told that once it's polished, waxing it, or clear coating it will help make it last longer. I have no idea what sort of clear coat process one needs to do to have it adhere to aluminum.

    The cleaner I mentioned is a acid that etches the metal "removes a small amount of material". Then you can polish the aluminum and the apply the inhibitor to seal the metal from oxidation and other environmental conditions. EPI is a industry leader in the metal finishing industry. I really like their products, because they work well and don't cost a ton. They also seem to last compared to other products on the market. Just one guys opinion.

    I use aluninum brighter. Mix it 2 times weaker than directed on the bottle to start. So a 40:1 to 80:1 ratio and mix into a pale. Use a wash brush to scrub the body of the truck. Do a small area and rinse as fast as possible. Repeat 3-5x's for maxium results. Once chemicially cleaned then polish at will using a polishing wheel and compound.
