In all fairness, you were told by a bike mechanic that that wouldn't work and that you needed to use glue. Sitting and ignoring the inconvenient advice until somebody chimes in with the advice you want to hear seems a bit disingenuous.
I'm just going to point out that if your tubular comes off your rim it won't be while you're trackstanding or doing a skid, it will be while you're turning a corner at 35mph. Seems like an idiotic risk to take because you want the convenience of using tape instead of glue

Yes, it's true: bike mechanics read the internet.

2. Stop being a dick.
3. I know plenty of people who would also call bull**** on your claim that "the tape is fail anyways." Seems to work just fine for plenty of people who are out there putting a ton of miles on their tubies.
4. Stop being a dick.
5. Even if you have some small amount of glue residue left on the rim, the tape will work just fine.
6. Stop being a dick.
7. Stop being a dick.
8. Stop being a dick.
9. Stop being a dick.
10. Stop being a dick.

"Do not use chemical paint strippers! They will attack the epoxy resin that holds your part together. Acetone, alcohol and other solvents are okay, but they don't remove paint."

Lennard,
That’s utter nonsense. Epoxies are rated in two standard tests: boiling in water and boiling in acetone. The rating calls out the amount of water or acetone absorbed. Epoxy does not dissolve in acetone. Acetone is a great solvent for uncured epoxy. But once it's cured, acetone doesn't hurt it.
The only problem with acetone as it relates to bikes is that it will dull paint and clear coats. Most bicycle parts are coated, sometimes with a satin or flat finish that looks like nude carbon. Acetone will change the glossiness (or lack thereof) and make you think it's doing something to the epoxy. Alcohol is the strongest solvent you can use that will not affect paint.
We offer frames in a nude finish and offer to strip all coatings off other carbon frames. Then we treat it with a UV filtering protectant (303 Protectant). Acetone cleans off this Scotch-guard-like treatment and it would need to be re-done.
That's more than you need to know about acetone!

My experiences with acetone involved dissolving various paints and coatings off of parts, so naturally I thought it would dissolve the epoxy resin as well. I stand corrected!

I've just spent an hour trying to scrape the glue off with a flat screwdriver and I'd say its actually only removed about 10% of the glue so far.
But apparently I can use acetone, so I guess I'll give that a try.
It seems like hardware stores like Home Depot sells acetone, but in bulk. Any suggestions as to where I can purchase some pure acetone? or maybe use nail polish remover?
Thanks for all the input guys (despite the ongoing debate here).
