Remove the old plastic mailbox from its post and give it a good cleaning with soapy water and a sponge. Rinse it well and let it dry completely.
Protect your surface with kraft paper or painter's drop cloth.
Apply first coat of Metal Effects Primer by Modern Masters. Apply with a sponge applicator in thin, light strokes to cover the entire mailbox.
Allow to dry at least 30 minutes.
Apply second coat of Primer. This time allow for a generous layer to fill in any missing areas of the first layer.
Allow to dry at least 30 more minutes.
Using a new sponge brush, apply a first coat of the special oxidizing bronze paint. This is where the ordinary plastic mailbox turns into a more high-end metal looking mailbox.
Dry mailbox for another 30 minutes.
For the final coat of bronze paint, apply in small sections at a time.
After applying a few strokes of paint, spritz the blue patina aging solution over the wet paint area.
Paint your mailbox post if it needs a refresh and reattach your mailbox! This would be a good time to replace old address numbers, too!
