I'm currently undergoing my first experience with tubs. Looked up the how-tos and ound two good Zipp videos:
Removing old tubs and glue

Putting new tubs on
https://www.youtube.com/watch?v=OGw3DlZMRGI
All that seems within my capabilities, but some questions:
At 3:12 in the first video, he recommends just keying the surface of the rim with 180-grit sandpaper -- "very light sanding". 180 grit seems coarse to me. Is that right?
I have three tubs that were originally glues onto my three rims. I want to do a practice run with one tub/wheel combo. Do I have to remove or reapply glue to the tub itself, or can I use the (possibly decades old) glue that's on there?
