So someone will correct me if wrong, but I think you would have to use etch primer (because aluminium) first then the smoothright after. But that said i don't believe smoothright has any temp rating?

Correct

If you want a lasting finish, you need an enamel. Dupli Colour and Simoniz are good it's the colour matching that can be an issue, if you only spray a casing etc. You've also got to ensure the prep is thorough, ideally soda blasted, primered and then top colour and baked, or it will start peeling inside a year if used regularly less in salt.
Oh and don't use the clear lacquers over the colour.
