changing grip without cutting old ones off

Hi guys, need some advice.

I'm about to regrip one of my scotty cameron putters but i don't want to damage the original grip.

i've read online that it's possible to remove grips using the airgun method, that wont destroy the old grips.

anyone knows where i can go to find someone who does this? or better still, if there are any 'home remedy' methods to DIY.

Thanks!

Go find Dgman....
