    Is the factory finish coming off to bare metal, or a subsequent paint job you put on?

    Quality 100% acrylic paint normally sticks well to either factory painted steel or aluminum siding which has somewhat oxidized (i.e. no longer super slick like the new factory paint) and has been cleaned of dirt and excess oxidation. If oxidation comes off on your hand when you wipe it over the surface, you should vigorously wash it with a pressure washer.

    If it is your paint job which is peeling, you should give it a really vigorous power washing in an effort to get that paint which is loose to let go. Remember, your next paint job is only as good as the adhesion of the paint you are going over.

    If it is peeling to bare metal, you will need to either scuff the surface or the metal with abrasives or etch it with acid. There are also self-etching primers on the market. Contact a good commercial paint store for advice as to materials.
