I think I should clarify my question. I am try to restore the factory finish on the alumimun engine, transmisson and chassis pieces.
As you are probably aware, since clean aluminum oxidizes so quickly, you have to coat it with something.
Parts other than the engine don't seem to get hot enough for paint to be a problem. My past efforts with painted valve covers haven't been particularly long-lived, but there does seem to be a wider range of aluminum paints available.
None of the parts you mention had smooth surfaces originally, so I don't see how a clear coat in a dull surface is going to look very good, but maybe there is something available that isn't shiny?
