in australia we have a brand of cheap spray paint called "australian export" which are like 2 bucks a can and already have calig caps on em so i just bought one and now i have my long awaited cap... :lol:
in the uk in a shop called parteners they have this stuff called photomount its got calig caps on it
if your going to buy the whole thing instead of stealing caps one use is to put some on your stickies making them waterproof
