whats a good material to extend the spoilers with?
Polymetal/Alumapanel/MaxMetal. All are a 3mm plastic sheet with aluminum skins and an enameled finish.

These samples were sheared, braked and rolled on a bench tool with an 18" lever arm, by hand. The brake was least successful as it burst the ouside skin. Perhaps not if the inside is scored beforehand.

I think a big advantage is that it's pre-finished.
