on a budget! would be a can or 2 of paint for £6 or leave it how it is.
to raw it i would need a wealth of sanding and nitromors, plus it will show up the little dent it has.
to bead blast i will need to pay someone to do it.
to paint i will need to rough up the surface, remove a few blemishes and then spray it.
to leave it as it is will cost me neither time nor money, but i'm not sure i like it lol
