Crustyness / 100 year old wiring
Clean well. Paint black. I used acrylic Homefront Decorator color I bought at Ace Hardware.
Tip: Use Satin or Flat black as an undercoat when dry-brushing. See how it
dries Matte (sconce on the left)? You want that. Picks up the paint better than glossy.
Dry-brush acrylic red over black lightly. Two times. Leave black showing in recesses and blotchy on flat areas. You can use any color combinations. I like these red, really modernizes them. But I want to take them back to metallic.
Very sparingly brush metallic gold over highlights and swiftly over flat areas. Accentuate dings. Leave details of black and red. One coat is fine, it is easy to over-do it. Then it looks over done. So stop while you are ahead. I consider this a bronze finish with a red twist.
Clear-coat with Satin finish. I found these pretty capiz-shell shades at Shades of Light
