A bit more on this:
Either one does, as far as I can tell, the exact same things that Wheelsmith spoke prep does, only:
1/2 fl oz for $20 or $40 per ounce
1 fluid ounce tube for $5
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?
