What can I use on an exterior door?

Citrus-Shield Premium Paste Wax is excellent for adding another layer of protection to exterior doors. On new doors, Citrus-Shield will extend the life of the door by adding a layer of protective waxes and a UV inhibitor to help protect the finish from the sun’s harmful rays. On older, faded doors, Citrus-Shield will return some color and shine, while still providing protection.
