genejockey Brute force works. I've yet to need to resort to tire irons too remove a tubular tire. As you've seen, adhesion to the edges goes a long way to minimizing the chance they roll off the rim.

DiabloScott I'm a glue
sniffer user. My only experience with tape has been trying to remove it.
I use paste/flux/welding brushes to apply the glue. With just a little experimentation you will quickly figure out the (light) pressure necessary to get the brush to fan out to the edges of the base tape or rim. Once installed, I pump the tire up to around 110psi to insure complete contact (edges and center).
