You should obtain it for free off the modeling guy at the peephole after completing the advertising quest. I did hear about one person who it was bugged for though.
I've finished that quest, nada. no latex.
How odd, sounds like it's a bug we need to fix. You might need to play through again, or wait for next update, sorry.
I'm fine replaying the entire game since I find it fun to play. no need to be sorry.
