I use gun oil on clean threads before I put the thread protector back on,the gunsmith said to use grease,but I was sure this would harbour bits of grit! So I went for oil instead! What do other people use?
i use molyncote grease (spelt something like that) its what divers use on the gear, i used it on my o rings on my bsa superten pcp airgun a few years ago and still have a tube left. its high temp stuff that doesnt melt.
one of the problems is that most lubricants are di-electric positive and attract dirt through static.You need a di-electric negative lubricant.
