Best way to polish/clean aluminum sides on Holiday Rambler

Depending on what shape and what the final finish is. If it is just polished aluminum, you can use an orbital polisher and jewlers rouge, (comes in bars of diffeent colors) and polish it until water beads up on the roof, then use Meguiars wax and or a better finish is ZEP High Traffic Floor finish. If it has clear coat of paint you have to remove it and then polish the surface out and recoat it with some type of protection.
