Like any painting the most important thing is preparation. I Use a wire brush on a drill, angle grinder or Dremel depending upon location. I then use Jenolite if any signs of rust remain. I then use thinners to clean followed by an acid etch primer such as U pol or Halfrauds do their own.
I used different types of paint depending on location. Plasticote, Hammerite or most branded paints are good.In some areas I use stonechip paint which can be painted over.
