    Hello all, after reading about what is needed in a spoke prep, and what makes wheelsmith's prefered, I came up with two seemingly suitable products from my years of working on cars. Thought I would ask here why they won't work, or if I'm on to something.

    Hylomar Universal Blue: originally developed as a special gasket material for jet engines, it is a . Some things that make it an ideal spoke prep:

    * Non Setting gasket/sealant
    * Unlimited assembly time.
    * Vibration resistant.
    * moisture proofing properties

    Distributed in the US by permatex:

    The other compound that would probably work is again a non hardening gasket type material. This one is older technology (around since the 40's) so probably isn't as good as the Hylomar. Permatex #3 (Sometimes called 3h), used to seal aircooled engine case halves together:

    thanks,

    A bit more on this:

    Either one does, as far as I can tell, the exact same things that Wheelsmith spoke prep does, only:

    Wheelsmith prep:
    1/2 fl oz for $20 or $40 per ounce

    Hylomar:
    1 fluid ounce tube for $5

    permatex #3
    16 fluid ounce jar for $6 or $0.37 per ounce!

    I would hazzard a guess that Wheelsmith spoke prep is a similar compund, only they have the manufacturer OEM it in a different color, or they buy it in bulk and just put it in their tubes. I will build my wheels with Hylomar or #3, I have some of both in the cabinet, but will buy the hylomar if I don't.

    Basically, what I'm saying is that the wheelsmith stuff is likely a huge ripoff, and then presenting a viable option. I would think that would spur some discussion?

    take care,

    Jester

    I dunno' d*ck about spoke prep.

    That said, I think you're looking at this in the right way: if you can get Manufacturer's Safety Data Sheets (MSDS), or equivalent, on each product . . . and the formulation is the same (where's CYCOCOMMUTE when you need him ), then you're looking at apples-to-apples. Then, it's just about the Benjamins.

    I just received my 8oz. bottle of Permatex nickel-based anti-seize (for use on my Ti bikes).

    Ti Prep is about $5 for 15g -- about $9.50/oz.

    At $20, the Permatex cost me $2.50/oz.
