    Assuming it's a metal garage door, you MUST sand it down. If not, it will peel, and you will not, not like that - as scraping loose paint off is no fun.

    You would have to prime any bare metal, probably with a special metals primer.

    You would then need to apply undercoat (oil-based best for metal IMO).

    Then topcoat. Oil-based gloss is best IMO, as will give a nice shiny hardwearing finish.

    ASSUMING you want to paint the entire door:-

    You sand ALL of the door.

    You have to take the 'shine' off the door all over, so you are left with a very flat, unglossy, smooth surface.

    This will provide a good key for the new paint to stick properly.

    If you only paint one panel it will stick out a mile
