Painting a hand rail

[Phil TK]

If it's aluminium and back to the metal spray it with a proper primer first, lightly sand and then spray with smoothrite. Multiples of light coats rather than a couple of thick ones gives a better finish, with smoothrite (or Hammerite) I think you have to do all the coats the same day because they 'cure' overnight and won't take kindly to another coat on top afterwoods. Or something.
