How has had luck with decent matches with rattle can paint? I'm looking for something similar to Silverstone Metallic PS5. Dupli color, or any other brands. It's going on the roof so it won't be too noticeable, but something close matching is always best.

 

You can probably find an exact match using your paint code, but that's a match based on when your paint left the factory. Ageing, sun fade and such might change things.
