I did a repeat on the test below. Again, I used an Eliminator car that I had on the shelf. I did not re-prep either the wheels or axles, I just used it as is. The car weighed 5.1 ounces (a bit overweight). The axles were 92s and the wheels were the Jewkes wheels used in 2012. I set up the rear wheels, and never touched them again throughout all the test runs. I.e. I only changed the DFW, and ran every test without ever re-prepping the wheels or the axle. I made sure each run used the same drift (steer). I ran each setup at least six times, and throughout the best and worst test run to get the average.
1. 2.9432 was with sanded wood only.
2. 2.9407 I painted the Teflon Nail Polish over the top of the wood in 1.
3. 2.9394 I painted the Teflon Nail Polish over the top of a Derlin washer
4. 2.9390 This test used only a Derlin Washer
5. 2.9380 This test used only MonoKote over the wheel hole. No washers at all.
6. 2.9365 This test used only a Teflon Washer/
7. 2.9350 In this test I painted Teflon Nail Polish over the Teflon washer in 6.
My opinion is that the test was mostly worthless because:
The margin of statistical error would invalidate most of the tests. I.e. results just happenstance
But, Teflon Nail Polish really does improve chances, at least in BSA races
I should have re-prepped wheels and nails between each set of tests
The temperature changed. I started at noon, and finished at 10 PM. At least a 15 or more difference
When a Teflon washer beat a Derlin, that didn't make sense.
One of these days I will try this again, but maybe with tighter prep conditions, and with an SS car with better products. I.e. the wheels used were not that great.
Maybe post your opinion on how I should run the tests next time that would make it more valid.
However, there you go. Make of it what you will.

Forget the washers. Just use Teflon Clear Coat after sanding the side of the car fine.
Since it's a fingernail polish, it has a small brush in the bottle. The stuff is only 2 or 3 $s a bottle.
Just paint 1/2 inch over the body holes.
Here is what I tested on my SS car Red Flag:
Fastest on top
Slowest on Bottom
1 Teflon Clear coat
2 glued on Teflon washer (slower by 1/100th)
3 MonoKote rolled up the sides (5/1000 slower than number 2)
4 Teflon loose washer (was equal to 3)
5 Only paint (1/100th slower than 3 and 4)
6 Wood Only -- Didn't test this
IMPORTANT POINT: I did this testing several months ago, and no longer have the documentation.
The times above are from my memory, and are inexact. However, the order indicated above is accurate.
Just to be clear.
I only used the Teflon polish on the car body. I never used it on the wheel bores. Never thought of it, but if you try, better use it on a set of older wheels that you can throw away.
Sometime in the next two weeks, I am going to do the test again and post the times.
