I have 2 different glues that I've been working with over the past week. One is Pastali, and the other is Pana Cement by Panaracer. When I was using the Pastali glue, I botched the job (due to an excessive amount of old glue on the wheel). So, I removed the tire, stripped all the old stuff off and started fresh, using Pana Cement. The Pana Cement seems to have gone on much better, and has a much firmer feel to it, while the Pastali glue (on the tire that I botched) is still very tacky and soft...it hasn't hardened at all. Is this normal? Is Pastali glue crap, or is the Pana Cement just that much better?
