i have always gotten paint back when i loaned my gun, thought ppl just realized that...
but as we all know, some friends are moochers, and u can usually think to urself, "hey he probably won't give me any paint back"
Well today a guy on my team ran out of air. So i was like wana use my gun? He said ya so i gave it to him. After he gave it to me with a empty hopper (i gave it to him with a full pod in it). All i had was 3 pods on my back ( end of the day so i had no paint at all left). So i asked for my paint back. But is there a rule? If the person ask for a gun he pays it back. But if u volunteer your gun then he dose not have to pay it back?
lesson learned. nice guys finish last. look out for yourself kid.
