The Powder Coating Process
We have been asked many times, "What is involved in Powder Coating a part?"
The process involves taking the parts and Sand Blasting, Glass Beading or Plastic Blasting them to remove old coatings and contaminants first. Then the part is either polished, Chromate coated or Phosphate coated to prevent surface rust and help adhesion. Then, if the part has any critical areas that need to be masked and / or plugged to prevent excess powder from getting into threaded holes or onto gasket surfaces, this is done. The part is then prepped again, coated with the proper color powder and cured. If a top coat is then required, as in the case with Translucent colors being applied over a non-chrome or un-polished surface, the proper color top coat is applied and the part is cured again.

Below are some examples of parts that we get in various stages, from brand new to needing quite a bit of prep work before powder can be applied properly.


Brass fittings new and bead blasted


Fittings Chrome then Translucent Blue Powder Coated



Intake Manifold after Bead Blasting

This is the condition the Cobra Valve Covers were in when they were taken off the car. The factory used Wrinkle Paint not Powder and it had all but peeled off

These West Coast Chopper parts are some of the best machined parts we have seen, and their polishing and chrome work are second to none. This is the type of material Powder Coating loves to stick to.


Here are the same parts after prep, masking and coating in High Gloss Black Powder.

The Blue Sparkle color Powder on the lower A-arms for this Quad was custom blended in house to produce a beautiful shimmering Blue effect in sunlight
The Chopper frame below was extended by 5 inches and then neglected for quite a few years. As you can see it was quite a mess when it arrived. After Chrome removal, Plastic and Bead blasting the frame was ready to be coated in Candy Red Powder and cured.

Now with Candy Red Powder, it looks better than new
