[Closed] 'Raw' aluminium frames - what coating?

Quite keen on going raw on an alu frame, has anyone (successfully) done this, and what treatment did you use on the frame? I'm guessing a clear matt lacquer will be required?

Will it need any further prep after sand blastign to remove the old finish, or will this be sufficient? (I'd be happy with a slightly 'distressed' look, and it would match my own )
