Repainting exterior metal doors

I have two exterior doors that the previous owner painted. I believe they were primed steel doors. The paint they put on feels sticky. I want to paint them a different color. Do I need to do anything to them before I paint another color on them?

Thanks

Need to degrease, very light sand, clean again then paint with a quality latex paint.
DO not paint them a dark color if there in the direct sun!

Most steel door manufactures state the doors should only be painted with latex. Some of the cheaper latex enamels will stay tacky around the weatherstripping Tackiness elsewhere usually indicated oils or some other contaminate on the door. Cleaning, sanding and applying a quality latex paint is the fix. Be sure to rinse off the cleaner that you use.

Ok Thanks Again ! I was hoping I didn't have to sand. What is the reason to not paint the door a dark color?

Dark colors absorb sunlight better so the door will expand and contract much more with changes in temperature as a result, this is hard on the paint.

The biggest reason you are supposed to paint most modern steel doors with latex is because the metal is thin. Latex paint will flex a tad, oil will not. As SS said, dark colors make the expansion/contraction worse.
