Powder coating is a type of painting process that is done by spraying a flour-like substance out of a paint gun. The dry flour-like paint is cured in an oven where the paint becomes hard and glossy looking. This paint is very strong, scratch resistant and long lasting.
Remove old coats of paint and corrosion from the metal part that you plan on powder coating. A wire brush works for corrosion and paint thinner works for old paint coats. Corrosion or old paint would keep the powder coat from giving your piece a smooth finish and making it look brand new.
Clean the part with lacquer thinner after removing the corrosion and dry it with a soft cloth.

Preheat your oven to 400 degrees Fahrenheit.
Mask off areas of your part that you don't want powder-coated, using masking tape. The powder coat is very difficult to remove, so make sure you know where the paint is supposed to go.
Hang the part to be coated. ou could set it on a smooth surface, but hanging usually works best and avoids any marks from a rack or table.
Choose the color paint and load it into the cup of your powder-coating gun.
Use your powder paint gun to spray the paint all over the part till a nice even coat is achieved.
Remove the masking tape before placing the part in the curing oven.
Carefully put it in the preheated oven and check every few minutes. When the paint looks wet and glossy all over, allow 20 minutes for the curing process.
