painters tape works quite well.
Can be a pita to replace as you need to be really precise when matching strips.
Try gluesticks as well. easier to apply, cheap and easy to remove and clean up.

Like most new 3d printer owners I went through the whole lot: glass, abs juice, hairspray, tape, pva and settled on printbite - that does need a heated bed, so no good to you.
Pva I found the best both for adhesion, application and relatively easy to remove.
