Your Guide to Choosing the Best Black Finish Coating 

What Does Black Oxide Finish Do? 

To understand why a black finish coating is necessary, it’s important to understand its purpose. Cleveland Black Oxide explains that “The black oxide process is a chemical conversion coating… the black oxide coating is produced by a chemical reaction between the iron on the surface of the ferrous metal and the oxidizing salts present in the black oxide solution.”  

This chemical reaction results in a black oxide finish, which has a variety of benefits from corrosion protection to enhancing the aesthetic appeal of your bike.

Choosing the right black finish coating for your motorbike depends on your protection goals and desired finish. PJ1 Powersports offer four specialty black finishes. We’ve listed each with a brief description below: 

  • PJ1 Fast Black Epoxy Paint: Provides a high gloss, porcelain-hard finish for all motorcycle frames and other metal components that require a factory-like durable finish. PJ1 is easy to apply, chip and scratchresistant, and guards against rust and corrosion. 
  • PJ1 Fast Black Engine and Case PaintThis coating was developed for all 2-stroke and 4-stroke motorcycle engine cases, cylinders and heads. It’s available in both gloss and satin, applies easily in a onestep process, and provides a smooth factory-like durable finish. It also resists chipping and scratching, restoring old engine components to a factory-like finish. 
  • PJ1 Fast Black Texture PaintThis coating was developed for use on various parts of any motorcycle (engine cases, cylinders, frames, etc.) where you want to achieve a durable textured coating that you can see and feel. It applies easily and provides an extremely durable textured finish resisting chipping and scratching. Dirt and mud easily wash right off with soap and water. 
  • PJ1 Fast Black HighTemperature PaintThis coating was originally formulated for use on reentry spacecrafts. As a silica-ceramic hybrid, it moves with the metal as it heats/expands and cools/contracts to give it durability. PJ1 produces a like-new flat finish, forms a protective shield against rust and corrosion, and resists chipping and scratching.

  1. Tipped over my – GS R1250. Thing weighs 600lbs. It happens! Scratched the matte black finish on my engine guards. Want to sand and then touch up the scrapes. Any DIY tips? Which PJ product should I use? Thank you. Glenn

    1. Glenn-

      We understand. It happens! The best product to use for your touch up project is the PJ1 Fast Black Engine & Case Paint (Satin). After finely sanding the surface and removing any imperfections, we recommend applying multiple light coats to the engine guards as opposed to heavier coats. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!


  2. I purchased a new bike, but alot of the metalwork around the engine has a thin layer of rust from the elements. Would I be able to buff and spray the entire mechanics?

    1. Jon-

      Based on your description, it would be both safe and recommended to clean the rust elements found around the engine on your new bike. The PJ1 Spray & Wash Degreaser(Part #15-20) would be the best product to use. Be sure not to clean the bike in direct sunlight and make sure to avoid spraying air cleaner and ignition.

      Thank you!
