One reason to use rubber cement IS the weak bond. It helps prevent damage to the blade when removing rubber (though you should varnish the blade regardless). I can't say I've had any worse luck with sheets peeling when boosting when using rubber cement, though. Just wait until the glue on the rubber is dry enough. If it's still gooey it'll peel off with the slightest dome. If you can't wait, add another layer of rubber cement on the sponge and wait for that to dry (it takes a few minutes).
Incidentally, I came across these on AliExpress:
