Tubular Gluing

First off, I dont need an explinatipon on installing tubies. I have way too many years experience on it. In a variety of technicques.

Problem, for track I glue the tires with the intention of them not coming off. IE it takes the better part of an hour to remove one. Trouble Ive found and several other have too is that the backing tape is seperating from the tire and sticking to the glue. These are mid range track tires designed to last unlike ultra light silkies. Vittoria Pista CS's, Conti Sprinters etc.

Can a decent tubie be glued directly to the underside of the tire and stitching? Has it been done? I imagin just as normal a light layer of glue would have to be applied to the tire first and let dry.

If regular mastiq wont work for this, what will? Ive heard of several cases of racers using carpet glue.

thanks for any ideas! Thanks guys and gals.

I've found the 3M Fastak Super Weatherstripping adhesive found at auto-parts store works great for holding the base-tape to the tyre. Can also be used to glue the tyre to the rim too, but as you've found out, removal with such strong adhesive becomes a problem later.

Fastack (in it's current incarnation) will cause basetape/carcass seperation.
One theory I read (and I believe that someone who worked for 3M confirmed it),
is that the base tape allows water to seep in and eventually breaks down the
bond, and that the chemicals in the fastack facilitate the process.
I recommend finding Soyo glue (or panasonic, same formula) which
is intended for Keirin/track tires. Other than that I use Continental glue.

It's probably the solvents in the Fastak. If you use it first to glue the tyre to the rim, some might soak through the base-tape and soften the factory glue. Since the Fastak is stronger than the soft glue used to hold the base-tape to the tyre, when you remove, the base-tape may remain stuck to the rim.

In this case, using the stronger Fastak to re-glue the base-tape to the tyre would end up being stronger than the original glue. However, you'll have to cut the tyre off the rim when you want to remove it...
