• Duplicating An Original Bronze/Green Carb Finish
  If upon disassembly you notice a green tint in the carb plating, use the appropriate mix of HotCoat brand Translucent Green and Gold powders. The mixture of these two colors will result in a bronze finish which is tinted green. We have found that to achieve the correct dichromate (bronze/green), a 50/50 mix of Translucent Green (Item #10155) and Gold (Item #10163) is required. The finish that results matches the Rochester, Carter and Holley brand carbs. Approximately 4 tablespoons of Translucent Green and 4 tablespoons of Sun Gold thoroughly mixed together in the powder coating gun cup will do the trick.
• Duplicating An Original Bronze Carb Finish If when you examine the disassembled carburetor you find the plating does not have a green tint, use the HotCoat brand Sun Gold powder to attain a like-new bronze carb finish. The Gold (Item #10163) powder duplicates Eastwood's Bronze Carb Renew liquid coating (Item #10044 Z). It also matches most Holley two- and four-barrel applications (particularly Holley model 4150).
• Duplicating An Original Silver Carb Finish We have found that the Cast Aluminum powder (Item #10097) is best for re-creating a silver look because it is a matte finish, which is closer to the correct original finish.
• Creating a Custom Carb Color Naturally, you can use any of the available colors to protect and beautify your carb. Whichever powder you select, you will need to follow these step-by-step instructions to help achieve professional quality results.

Steps For Powder Coating Carburetors

1. Completely disassemble the carb, removing all gaskets, seals and plastic floats. You have your main components once the carb is disassembled: throttle body, air horn, base and float bowls. Linkage components can be powder coated with HotCoat's Stamped Steel (Item #10099) powder. (Remember, only the metal components of the carb can be powder coated.) Other options include: using Detail Gray (Aerosol Item #10036Z, Quart Item #10046ZP) or Eastwood'sTin Zinc Electroplating Kit (Item-no #10049Z).
2. Thoroughly clean all components to be powder coated with Pre Painting Prep (Item #10041 Z).
3. Allow parts to dry once all contaminants are removed.
4. Preheat parts in non-food prep oven for 20 minutes at 400ºF. This will drive all contaminants, hidden in the pores of the metal, to the surface.
5. Remove parts from the oven and allow to cool. Clean again using a clean rag along with Pre Painting Prep. Repeat this preheating and cleaning procedure until no dirt nor residue shows on a clean rag.
6. Burnish the surface of the components with a Scotch-Brite® pad to produce an even finish.
7. Again clean the components with Pre Painting Prep.
8. Using High Temp Plugs (Item #10078), High Temp Tape (Item-no #10027), and aluminum foil, mask off and plug all critical threaded holes, metering ports, gasket surfaces and throttle body venturi surfaces. Your components are now ready for powder coating.
9. Suspend parts from your oven rack as stated in the HotCoat instruction manual. Follow the HotCoat instruction manual for applying the powder and curing for professional results.
