How do I put grips on mountain bike handlebars? I just spent the last 10 minutes trying to put a new set of grips on to my mountain bike handlebars..

The old ones came off fairly agreeably and I've got the new ones 80-90% of the way on, however, at this point both my hands are stinging from the aggressive twisting and pushing - I have tried gloves, but I feel it's best left till my hands don't hurt anymore.

Is there a tried and tested way of doing this? Or is there a knack to this that I am missing?
Two solutions I've used:


Spray the inside of the grip with hair spray. Slide it on immediately, and then when the hair spray dries, it will glue the grip in place. 
Use rubbing alcohol. It does not do as good of a job at locking the grip in place, but it does evaporate quickly and doesn't leave any lubricant inside the grip.
