This one is probably the best.
Q:Is it legal for me to spray paint my airsoft guns into any colour?
A:Yes,but only if it's spring action. In Canada you must leave a orange cap/tip on and if you do spray paint the gun never ever show it in the public or point it at a police officer or the police will deal it as a real situation.
SO if I don't paint it, its totally OK to point it at cops! SWEET
