Stove vent, outside shower, water heater and furnace doors.
i've been wanting to upgrade the look of these exterior attachments for some time. There are stainless up grades for both the water heater and furnace plus the stove vent and the outside shower. Problem is cost. The OEM stove vent is a white plastic with a rubberized type of gray paint. The furnace and H2O heater are metal doors painted dull gray. Shower unit is dull gray paint that chips off easily leaving white plastic. Here are the two doors and outside shower unit spray painted with the same paint I've had good luck using to repair areas of the skin where the clear coat has been removed, as in corrosion repair. Easy to remove the doors via clips and the screens pop out from the back. Sand lightly with 1000 black paper, clean and spray. Paint drys in 30 min. I bit the bullet for stainless stove vent since no way a repaint would stick. The rest is a good upgrade until you decide you want to go all stainless--if ever.
Paint: Rust-Oleum, Metallic, brilliant metal finish, code 7271 silver metallic.
