Been polishing aluminum for near 40 yrs,it's all about knowing how to do it and having the right tools.Once you achieve the finish you need use a good polishing cream once in the spring and just before storage.Have found over the years that just before storage polishing is not really required.The cream I prefer because of it's ease of use is AutoSol.
If the luster goes away for my required finish 600 grit paper works for me.Some need a finer finish all the way to buffing with rouge.
Some prefer a finish,I do not.Once the finish is comprimised then it is a chore to get it all off and have to start all over.We all march to a different beat.
