For the rack I’ve been working on previously, I decided the rust and tarnish wasn’t acceptable and I should repaint it.
I know I could easily send it away and have it spraypainted (or even powder coated) professionally for not too much, but I’ve never sprayed metal before and I decided to use this as a learning exercise.
Here’s the steps involved I used. If I wanted to I could have done a lot more afterwards with cutting and polishing, but I was happy with the effect.
- Clean the surface, remove all dust/cobwebs/dirt, etc
- Wipe the surface with isopropyl alcohol.
- Sand the metal with 80 grit sand paper, remove any trace of rust
- Sand the metal with 180 grit sand paper, remove any trace of previous scratch marks, etc.
- Sand the metal with 400 grit sand paper
- Clean with isopropyl alcohol again (some people suggest priming the metal after this step, but my paint is an all-in-one and I decided to skip this)
- Wet sand with 600 grit sand paper (wear latex gloves to stop oil from your hands)
- Wet sand with 800 grit sand paper (wear latex gloves to stop oil from your hands)
- apply paint per instructions, I used 2 coats separated by an hour, with little bits of touching up where needed.
Here’s what it looked like when I stripped it all down and started sanding:
The side panels being painted;
The main frame being painted:
Painted and reassembled;
Close up on the various colours. The finish isn’t perfect, but I’m pretty happy with it for a first go. The hammertone on the top and sides came out nicely too.
And reassembled and powered up:
I know what you’re thinking, and yes; This smart, elegant set of atomic clocks would be a tasteful addition to any living room.
All the sanding was pretty tiresome, but totally worth it. All up it was less than a week to go from getting the rack to having it re-painted and assembled in my house.
