As a project for the summer I want to repaint the metal banister/railings leading from my floor to the ground as now all but one of the flats in my block are now privately owned rather than council owned we are now responsible for maintenance though the council would still be responsible for a share as they still retain ownership of one flat. There is no rust to be concerned about but the old paint is certainly well chipped and worn. So am looking to sand it to a reasonable condition but not spend that much time doing so, then priming and adding a final coat. So what grit paper? Will any primer do? What about final coat? This is an odd job for me to be taking on as last year when I finally finished redecorating, refurnishing the whole flat I vowed at 64 I would never ever need to touch a paint bruch, pasting table again in my life as I hated it.
