Seal the Wheel Bores to Improve performance!

What is a sealer? A sealer is a synthetic protectant that works a lot like wax but has a better chemical makeup. Tests show that using the Pro-Wheel Bore Sealer on the bore of your wheels will improve pinewood derby car performance when using Max-V-Lube Graphite or when using Krytox 100. Using Pro-Wheel Bore Sealer will reduce the coefficient of friction, allowing the wheels to spin faster and more freely. This equates to improved performance on the track.

Pro-Wheel Bore Sealer Instructions

Pro-Wheel Bore Sealer works best after the wheel bores have been polished with Bore Polish. Sealing the bore is the last step in wheel preparation before lubricating the wheels.

  1. Apply a small dab of Pro-Wheel Bore Sealer to a piece of the narrow pipe cleaner.
  2. Slide the pipe cleaner into a wheel bore and rotate the pipe cleaner so that the bore of the wheel is completely coated with sealer.
  3. Remove the pipe cleaner and set the wheel aside.
  4. In the same way, apply sealer to the other three wheels.
  5. Insert a clean piece of the wide pipe cleaner into the bore of a wheel.
  6. Move the pipe cleaner back and forth to buff the sealer.
  7. Repeat for the other three wheels.
  8. Buff any sealer on the hubs as needed with a soft cloth.
  9. Lubricate the wheels as per the manufacturers instructions.

From Randy:
“In our experiments, the use of Wheel Bore Polish followed by Pro-Wheel Bore Sealer improved wheel spin times for both Max-V-Lube and Krytox 100 lubes.”
