What is the best way to finish metal so it can be clear coated.
some of the projects i've tried in the past have rusted under the clear coating?

Try galvanizing it with nickel or zinc. Paulo

Clear coating

I don't know how big of a surface you are doing, but I have on some reflective metals Powder Coated them in High Gloss Clear to not worry about rust problems.
