PU Coating or any other clear organic coating on Aluminium

Hi, I am a First Generation entrepreneur, and I would like to start another workshop on the metal Aluminium. I already have an Anodizing Shop, and I would like to start another coating (PU coating, or any other organic coating) shop.

I wanted some expert advice from you experts. Can PU be coated on a thin (0.4 mm) Aluminium Sheet? Also the layer of the PU Coat should not exceed 5 microns, since I want to preserve the surface finish as it is.

Is there any other coating available which can protect the surface, and also do not change much on the surface finish?

My main aim is to provide Good surface appearance, aesthetic value, corrosion protection & long life to potential clients in various fields. In simple terms, I am looking for an alternative to Clear Anodizing.

I am sure the info that I require would be available with you experienced people.
