try a local stationary shop or halords, i'm sure i've seen it somwhere like that, B&Q should do it too.
no point spending the extra dollar on 3m, just buy the cheapest spray glue you can find, depending on what your doing though. if its for a poster or something, make some wheatpaste, then that poster aint never comin off
I've had other spray glues and it's no good. The stuff on Ebay isn't really what i need. It's for posters and shit like that. Mines for plastic and fabric and shizzle
if it doesnt have to be clear then use wheatpaste, what i used to use when i did postups and they would never come off unless they were burnt off.
