Rachel convinced me that our red door wasn't working for us. She picked some bright blue from the Martha Stewart Home Depot paint lineup and I repainted it. Gave it a light sanding to remove some of the old paint drips, and some bondo to patch some dings and dents in the wood. Found it easiest to use a weenie roller on the flat front sections and a 2" brush for all of the edges. Let it dry all day with the door open (letting in all of the Sacramento summer).
Then replaced the old tired and worn hardware with a new handle and deadbolt from Emigh hardware. The Ace brand was much cheaper than the equivalent Schlage or Kwikset.
