Mechanical Polish/Wax for Aluminium Van

Hi team,

Interested to hear everyone's (well, maybe not everyone's...) experience/tricks for polishing/waxing an aluminium-sided caravan.

Two different types of alloy sheeting. The front and roof is a stippled rough surface and the sides are smooth, longitudinal ribbed aluminium (white).

Surfaces are in good condition. Roof has some oxidation and the sides are still pretty shiny. I want to bring it back then maintain with routine waxing.

I'm not after an aggressive cut. I think a mild 'cleaner wax' will be more than sufficient. Something like: Meguiar's Wet Look Liquid Cleaner Wax.

Can these vans be mechanically polished without risk of cutting through on the high spots??

I have a dual-action polisher (which I know how to use) and a range of foam pads. I thought the softest black pad on low speed might be OK without risk of polishing through the very thin coatings? Though I'd probably need to finish by hand along under the ribbing.

Cheers,
