Along with the problems you cite, I recall discovering that Jantex rim tape allowed more tire creep on long descents with lots of braking when compared to a proper glue job. So, after a few experiments with rim tape, including gluing it to the rim as you write, I kept gluing on tubulars in the normal fashion. It took longer, but it held the tire on better in all situations if done properly, IMHO. As to the brand of glue, I always felt Tubasti was inferior stuff compared to red Clement road glue too. (Used 3M #8031 for track applications.) Under hard braking on mountain descents with Tubasti, the tire seemed to roll more suddenly, while the Clement allowed some creep and warned the rider things were getting too hot. When installing a spare tire after a puncture, the Clement held it better and quicker, while the Tubasti took longer to set up and ride safely. In terms of initial application with a new tire, Tubasti might have been a little more forgiving to the novice.
