    Default OT Powder Coating Question

    I'm trying to avoid repainting my front door (it is gloss black). The door faces S.E. so it gets pretty intense morning sun here in SoCal, which is hard on the paint. So I am thinking of getting a steel clad door and having it powder coated. The offering from HD spec's galvanized and primed. Simply powder coating over this would be ideal. If the primer must go, ok, but if galvanizing is a problem...?

    I think that most metal doors are styrofoam filled. That might not work so well in the powder coat oven where it reaches around 400 degrees F.

    Also, check with the type of powder coating itself. I expect the problem with your S.E facing door is UV and I'm not sure if powder coating has any better UV durability.

    An HVLP spray gun and a little practice would be less expensive than a new door.

    You wont be able to powder that. You could make a facade for it though, powder that and somehow attach.

    Steel doors get dents in them. Fiberglas doesn't.

    Well yes, steel dents. But fiberglass cracks.

    Both are bad. Both are repairable.

    Maybe a urethane based, uv-resistant marine paint would be appropriate? But yeah, powder isn't going to work for an insulated door.

    Yes, they are foam filled. That’s what makes them more energy efficient.
    if I recall correctly, powder coating requires bare metal. So, both primed and galvanized would be a problem. Unless the galvanized is the non-oil type (aka Paintgrip) the powder coat would have adherence issues.

    I think a powder coater using polyester or urethane powder and a radiant oven would be able to coat your door. Not so sure about adhearnce issues.
