So I’m preparing some tubular wheels for next season and I can’t really see the difference between the normal players (Continental Special Rim Cement or Vittoria Mastik One) and off-the-shelf “rubber cement” that you buy at the hardware store. They don’t pass my sniffing test 
Is it the final strength or stiffness/hardness?
Is it the heat resistance?
Or is it just the cost (10x)?
Zipp reccomended to me using Mastik on their rims as they had the best adhesion and lowest rolling resistance. You also need some heat resistance as carbon heats up rapidly under braking.
Given the infrequency of application, the catastrophic results of tire rolling and the high cost of purchasing tubular race wheels and tires I would say just use the Mastik and use a lot.

I would hate to find out the difference between the types of glue by rolling a tire. I’ve heard overwhelming praise, especially from track riders for Mastik One, so that’s what I use. There are different ways to glue a tire as well, depending on the type of riding you’ll be doing. Track rider’s don’t have to worry about removing a tubular easily to change it in the middle of a race, so their tires are on there pretty tight.
Given the relative cost of the glue to everything else in this sport it isn’t worth the risk. Use the best: Mastik.
All of you, I agree there is little incentive to use anything but the best.
But…
If I glue a tubular tire the only way that makes sense, with massive amounts of glue, there is an automatic “check” whether the tire will stick or roll: it’s almost impossible to get off.
This property is easily checked when using “rubber cement”. If I can get it undone with my bare hands in less than, say 10 minutes, it’s not strong enough.
Second, at three tubes of glue per tire, the cost becomes “non-neglible”. Like $20+ per tire (from where I’m sitting). I know - it’s not much.
But if the “rubber cement” does the same job it’s like $2.
Third, if “rubber cement” in general can mean all kinds of qualities and properties, it makes sense for everyone in the industry to only recommend a recognized product. But there are stories of people using 3M FastTack with excellent results. So my guess is that is it possible to find “rubber cement” at bulk that is ~as good. I was hoping for someone in the know to reassure me on that 
Three tubes of glue per tire ??? Then what am I doing wrong? I get two to three tires per tube of glue.
Where have you been?
cheap used and abused tubie wheels = ~$200 (complete guess here)
winter beater bike = kinda free or <$400
helmet/knee pads/elbow pads = $200
tubies = $40/ea
jar of rubber cement at walmart = $1.97
video from “friend” or you testing “roll over” resistance in parking lot = priceless
(i just wanted to type that up, i’m with you as it very well may work. it’s just when it doesn’t, and good stuff has failed also ask LA, it’s going to suck.)
