Ok i am gonna give this a shot i have a 10litr packet of luminous yellow Natrosol that has not been opened and is nearly 4 years old not sure if gunge has a shelf life just not sure what to do with it i do not see the point of using it on myself cos i will not see the enjoyment in it and filming it myself will be problematic so i am thinking about selling it but not sure this site is the perfect place to do it but with it being a WAM based site you never know so if someone wants to make me a offer then i will accept please message me guys if anyone interested
