HOW TO POWDER COAT  
1. Properly prep your piece:

You must remove any corrosion or previous coatings before
powder coating. Just as you would prep the part for a high
quality paint job. Corrosion can be removed with abrasive
blasting, wire brush or chemicals. Pervious coatings can easily
be removed with liquid paint stripper

2. Properly clean your piece:
After you have removed any corrosion or coatings
thoroughly wipe down the part with lacquer thinner
or acetone to completely remove any
residual grease or oils

3. Masking:
You must mask any areas where you do not want powder.
Powder is very durable and therefore it is very tough to
remove. The supplied tape is used to mask areas and the
plugs will mask any threaded holes.
NOTE: The masking tape and plugs are applied before powder
application and removed after the oven cure and cool down.
TIP: Tip mask large areas you can use aluminum foil along with
the masking tape.

4. Part hanging::  
Parts can either be hung from below the oven rack or set on
top. Just as with liquid coating if any area of the part touches
the oven rack lit will leave a mark, so you best finish is
obtained by hanging below the rack with the supplied hooks.
TIP: You can also use un-coated coat hangers or steel wire to
hang parts

5. Spraying
Powder application is very simple and straightforward. Simply
fill the powder cup with your desired color of powder and spray!

6. Curing
The powder must be heat cured to transform it from a solid
powder (similar to flour) into a gel state that allows the particles
to melt and adhere to the surface. This operation MUST be
performed in a non-food prep oven. The oven is preheated to
400F; once the part is powder coated carefully move the oven
rack into the oven. Check the part every 5 minutes until the
ENTIRE part has turned from a dry powder state to the gel
state (this is easily identified as the powder will be glossy and
look wet). Once this happens set your timer for 20 minutes.
Once cured allow the part to cure and put back in service
TIP: Small toaster ovens can be obtained for about $20 or
even less at flea markets. Start with this size and then keep
your eyes open for associates, friends, etc that are upgrading
their kitchen oven. Once you start powder coating you will
realize the benefits, ease and want to do larger parts!

What can be powder coated:
Essentially any metal object that can withstand the 400 F cure
temperature can be powder coated. Objects that have
gaskets, wires, grease seals, bearings or plastic components
must first be disassembled to remove these components that
will not with stand the cure temperature
