I have a metal BBQ which has started to show some signs of surface rust. Before it gets too bad I thought I would repaint it. Do I need to treat the rust first before painting it? If so, what with as I assume it will need to be heat resistant?
I terms of paint, I assume I will need to spray it? If so, is it better to use an aerosol can or I have a battery airless paint sprayer (only works with water based paint).
Any top tips greatly appreciated.
