hahaha...yeah. street art is kind of my thing
when you say "cement" do you mean concrete-type cement? or something like rubber cement? (i don't know why, but i assumed you meant concrete when i replied last and totally forgot that i mentioned cement in my original post) the concrete type just woudn't be practical. i need to get in, post-up, and get out.
if you mean otherwise, i would definately be open to something like rubber cement. as long as i can fit it into a backpack or messenger bag and there is little, to no preparation time, it would definately be usable. what type of cement do you recommend? and i can't stress fast drying enough. hahaha. it's kind of hard to look inconspicuous standing around a giant picture frame at 4am.
