Default Clearcoat over polished aluminium?

This may be a stupid question (from a newbie) but can you put a clear coat over polished aluminium?

I was thinking of a polished look, but the cowling and FG tips have to be painted anyway so a design incorporating solid colour on these and extending over parts of the rest of the plane is required. Why not use a base coat and clear coat system and extend the clearcoat over the polished parts as well?

Is there a problem with adhesion, or a chemical reaction with the aluminium, or perhaps the polishing compounds can't be removed sufficiently to give a clean AND shiny surface for the clear coat?

As a related question, for those who have polished planes, how do you clean at the edges of the painted/polished surfaces without damaging or contaminating the other side of the line?
