Any tips appreciated gents. If touching up spots of chipped or flaking paint on a metal figure, is it always best to dab on primer first or just paint it onto metal , then varnish it afterwards ? Can varnish be used as the primer ( I read that somewhere )? I will be using brushes and acrylic paint, I don't have an airbrush. I have not painted figures since childhood, so will practice on old Airfix plastics first I think ( to work out thinning the paint before applying )
Thanks in advance.
