It's my first time doing this. I've seen a few videos, and they don't all do the same thing.
First was the Zipp video on youtube, where the guy uses 2-3 layers of glue on the rim (letting each dry for 24h), then 1 layer on the tire (letting that dry), then finally gluing the tire on with a final 5th layer of glue that has dried for about 5 min. And he waits like 2 days before riding.
Then there is some other guy that uses only 1 layer on the rim, 1 on the tire...letting those two dry completely, and then gluing it the 3rd time. 1 day to dry.
And finally, the instructions on my tubular glue that basically say: Clean rim. Apply thin coat and let dry for 5-20min. Mount tire and pump it up. Wait 12H before use.
The glue is Tubasti, it's French. This is the most extreme one
I think option #3 is not a good idea, but what about #2? I know #1 is definitely going to work...after a month.
My rim and tire have been glued previously, so there is some left on there. Do I still need to apply those extra coats on the rim and tire before doing the final gluing, or can I just put the glue on and mount the tire?
