Which Tubs?

Some people do away with the basetape completely, but I would advise against it if it's not too bad I would just glue it as you would any tub, and I would definitely advise against gluing the basetape to the tub.

What's the issue with gluing base tape back onto tub?
I do it with liquid latex (Fake skin from the joke shop)
Seems to work fine for long stretches of de-laminated basetape as well as short stretches of re-stitched repair.
