Several dive friends gave me regulators to overhaul because they have them and not dived it since several years.
All threads were sticky and with plastic 2nd stages the risk to crack the case trying to disassemble the valve is too high.
This happened to me in two ocassions. In the first the case was already broken and glued with cyanoacrilate. The second case it was my fault.
I've learned the lessons and since then I had good luck with this :
I covered the rounded part of the case with electric tape and put a clamp well tightened. With this I can make more force with the nut wrench.
