T200 gushing from trigger

[Natjeeling]

Having a mare with my t200 machine that I've had for 4 years no problems. Just spray tanned a friend and liquid was leaking from the trigger. I've gone through a full pot of tan just doing her and I was drenched.
I've taken it a part and cleaned but it's still leaking. It leaks even when trigger not pulled.
Anyone got any ideas?

I think Steve@Nouvatan's youtube clip about taking apart the gun may help you, I think it may be that your gland nut seal or gland nut needs adjusting.

3.18 of the video on should help (at 6.12 on he talks about the gland nut again).
