Welp, I'm working on getting my new one (Trek 560 Pro Series) ready to take out. I got the front tubular mounted no problem, and I got glue spread on the rear rim, but... I'm out of glue. Kind of. I *had* been using Vittoria tubular cement, of which I used all. I have half a tube of Tubasti left over from an earlier project. Is it OK to mix-n-match or will there be compatibility issues?

Common sense tells me to wait and get a new tube of Vittoria cement tomorrow. Impatience tells me to go ahead and see what happens. So I'm going to take the middle ground and see what a bunch of strangers who've no real interest in my health care premiums have to say about this.
