Because shiny objects seldom allow paint to bond well, use the metal brush and sandpaper to lightly scour and dull the surface till it looks lightly scratched, almost like brushed nickel.

Priming metal before painting is almost always recommended, as it will prevent rust from bleeding through the new paint. Primer also helps paint stick to metal.

Galvanize the metal.
