    I did some searching but didn't really find much info. on the subject of Zero Friction Side Glides. Is there an advantage to using Zero Friction Side Glides over Delrin axle washers? How are the Zero Friction Side Glides attached to the body? Epoxy or super glue? Do you have to notch the body for the glides? I would assume the axle holes would have to be drilled after the guides are attached?

    Thanks,
    Steve (MRB Racing)

    I have never tried this technique, but it seems a lot more difficult than using a Delrin or Teflon washer. Sorry, I don't have any more info for you/images/boards/smilies/frown.gif

    Steve,
    I glue mine on with super glue. Whether or not you need to notch the body depends on your front body width and how much front offset you need to keep the body centerline parallel to the guide. Same consideration you would have when adding the thickness of a Delrin washer.

    As for the question about which is faster, I don't think one is any quicker than the other, given the proper setup. I would test them both and see which one suits your style.

    Mr B. Here you go. This was my order from McMaster-Carr. Its a lot easier than the old method I used that I learned from "SpaceWalker" The back just peals off, however I've been adding super glue for extra strength. I will say this about the new stuff it's pretty darn slick and I actually spun my wheels on the car and turned them so they would rub on the teflon and they still keep going for several seconds afterwards. You can always use this in-conjugation with the washers too, which I know some builders do. Hope this helps. Thanks

    Do you glue the washers to the body or let them spin free between body and wheel

    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

    Holy Toledo!

    Opa, Thank you so much for such detailed data.

    After I read the Kinser post I thought "oh, this is good stuff".

    But yours is just outta the park.

    Best regards,

    Hey OPA could you show a link to this stuff on amazon. I found some "teflon tuff" by Helle Hanson. Is that what you tested? Thanks

    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.

    I will save you guys some R&D time on the Teflon Tuff nail polish. I have used it on scout cars for about 4 or 5 years now. In my mind it is only useful when washers are illegal. It is not faster than Teflon or Delrin washers . Yes I have run on league cars and didn't slow me down too much but a little. I thank there is more potential for speed gains with washers when you can use them. Testing nail polish and washers against each other could be misleading, because of some variables such as tuning for one. And yes, I have tried it in wheel bores on a set of 2.4 g retired wheels, and do not do it on a good set of DD4H wheels, cause you will be sorry!!!!!That's it in a nutshell[​IMG]

    Just to add to this discussion, we were scrambling last week looking for the Sally Hansen teflon coating as we put final touches on car pack race on Sat, but we couldn't find it at any of the drug stores.

    There must be 1,000 bottles of nail polish and there was a huge Sally Hansen section, but no teflon clear. I tested a top coat the wife had that was meant to provide a hard surface, and it caused more drag. We couldn't use washers or inserts for the pack race so I resorted to sanding the surface real smooth and then burnishing with graphite (only graphite allowed). Certainly not as good as teflon insert but I didn't trust trying to use one of the other types of top coats.

    When I searched for it, it looks like the Teflon Tuff has been discontinued. Lots of store still have some and it's available online though. I found this: http://www.amazon.com/Sally-Hansen-Triple-Advanced-Hardener-0-45/dp/B0046MLZWU

    I haven't tried it yet, but the ingredient list says it also contains PTFE. If I can find it locally, I'll give it a shot.
