I need to paint an insulated metal front door to match the trim on my house (light beige color). Factory seems to be a fairly glossy enamel, so I'll probably scuff and prime with Zinnser (which is compatible with both oil/latex). If I do this would it be OK then to use a latex house paint, or should I stay with oil? If oil/enamel, should I just go buy some spray cans then?
