    Are you kidding me?!

    I think I bought the wrong nail polish!!!

    Do you think Sally knows the hubub she has caused in the PWD community?

    I have to admit, it was a first for me.

    Not for nothing though, Opa brings up an interesting point. Even if the numbers are within the margin of error (and I don't mean to doubt your numbers, the point I am making is that the margin is slim), then this means that any surface can be painted with this stuff, and it will be pretty darn slick. Fascinating stuff.

    Opa,
    In your next round of tests please include polished Delrin. This stuff is so slippery, I can barely pick it up!

    I'd be curious how the PTFE filled Delrin would compare. The hard surface of the Delrin combined with the slippery PTFE seems like a good combo.

    I did a "sled test" using a BSA wheel turned on it's side and filled with 9 tungsten cubes. I pulled it across sheets of different materials using a small digital hanging scale (made for weighing letters). I tested PTFE, UHMW, & PTFE filled Delrin but have not yet tested plain Delrin.
    I thought for sure that the PTFE filled Delrin would test the best. It is very hard and feels very slick to the touch. Sadly, it tested with the most drag of the three. I'm not claiming to be duplicating race conditions here, but thought it would give me some comparison.
    I'm wondering how they would test if lubricated.

    I think you have the right idea about just using a Delrin washer. It's quick and easy to install. I used them on my car that I sent to the December race and my car was pretty quick.

    I have a set of the side guides but for now I'm going to continue with delrin washers and work on my race prep and car setup to get quicker.

    All good info in this post though!
    Thanks!

    I have to admit it was a bit uncomfortable as I trolled the aisles looking for the polish. And if I didn't get asked once I got asked 5 times if I needed help....No Dammit, I'm fine (grrr).

    I'd left the family in the car but I was taking so long that by the time I hit the door they were all coming in with my wife exclaiming at the door...'what, you couldn't find the nail polish you were looking for' (ugh).

    I went to Target last night to buy a bottle of this stuff. I guess the formula has been changed again because the ingredient list said it now includes titanium instead of teflon! I didn't buy it.

    Best to order it online. Then you only have to look at your wife eye to eye , and tell her what your using it for. "Its for your son dear"[​IMG][​IMG]...SPIRIT......

    Hey guys, quick question on nail polish for ya. Told my wife about the teflon tuff and she laughed at me, but this morning she had left a bottle of polish on the table for me! either she's climbing on the derby bandwagon or is being fececious and sarcastic. The polish is Sally Hensons diamond strength with platinum. Now I don't want to send the wrong signals to my boy Nic but it may be slick. I'd never hear the end of it if I went out and bought a bottle of nail polish. I'm gonna do a simple test for slick factor but wanted your expert opinions- think there may be something here?

    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.

    Amazing! Thanks so much sharing this info Opa!

    I am going to get some for the scout race.

    These numbers are so close I feel that you could run these tests over and over and still not come to a definitive conclusion as to which is truly fastest.

    There are so many factors, but I am convinced that it is in the running at the very least.

    If you do end up running more tests my only request (if the tests were not performed this way already) is to use a plug and play so that there is no way the steer could be altered.

    Wait a second. That would probably negate the tests since it would not duplicate usual race set up.

    Never mind. Thanks for being so sporting. You are a real philanthropist.

    I got some of the slide guide in the mail today. First impression, the washers feel slicker. I'll test it out in the February race.

    OPA, you are a testing machine, 10 hours worth, if I read that correctly. Wow! Thanks for your time and efforts to answer the question at hand.

    Opa,

    Want to make sure I’m reading this correct, but it looks like the MonoKote alone performed very well. I have some of this laying around, did you use the iron on or the adhesive backed MonoKote? I’m thinking this is the biggest bang for the buck without using washers.

    Interesting that the nail polish over the washer was faster than one or the other. What about nail polish over top the monokote?

    Question for those of you that used the Sally Hansen #1 Clean Teflon coat. Did you put of coat of hardener over top? It seem'd a little soft to me and was wondering if the hardener over top would help. Hardener has Teflon in it as well. Thanks
