But today, it has new life. It has been powder-coated.
Powder coating is a way to apply a very durable finish to metal parts. You basically spray tiny particles of plastic, which are charged with electricity, onto your part, which is also charged with electricity. The charge helps the powder to stick until you can put the whole thing in the oven, where you then melt the powder into a solid coating. It's actually pretty easy, if you have access to the right equipment.
What you will need:
- An angle grinder
- A sand-blaster (or a lot of time with sand-paper)
- Water and a pre-powder cleaner like TSP (Trisodium Phosphate)
- Powder (from Harbor Freight, or an online vendor like Columbia Coatings Inc.)
- A powder-coating gun system (these can be $100-$200 for the basic models. They plug into the wall and into an air supply (like an air compressor), and they spray the powder through a nozzle that charges it with electricity).
- An oven that will fit your part and can hold the temperature you need for your particular powder.
Step 1: Clean Up Rust / Old Paint
Step 2: Sand-Blast to Finish Clean-up
Step 3: Clean / Degrease With Water and TSP
Clean your part thoroughly with TSP or another recommended pre-powder cleaner. Rinse thoroughly with water.
Hang your part in the oven to dry thoroughly (30 minutes in my case).
