You're right, Selden rigging screw oil is now very hard to find. Last time I got some it was from Torresen.

Everyone I know now uses BoeShield T-9 on turnbuckles and pretty anything else that moves and gets wet. Boeing developed it as a waterproof lubricant for the aircraft industry. It totally rocks, and is probably the reason RSO is hard to find these days.

Anhydrous Lanolin... if you don't believe me, ask Brion Toss!
Obviously a good choice.

I personally (having used both) find it hard to apply, and it also does not penetrate, making disassembly necessary if you want to use it on turnbuckles and the like.

I know that the anhydrous type has all water removed from the lanolin and is in a paste form, yes hard to apply. You'd need to smear it on the turnbuckle threads and then screw/unscrew to work into threads, which could be bad if you have all your tension set just right and don't want to lose your tune.

The type of lanolin that has mineral oil in it, isn't there another name for that besides anhydrous or is the same? I thought that it had a more liquid/gel consistency... Am I confused on the two types?

Obviously a good choice.

Marelube. It is available in a syringe applicator as well that works nicely for applying to threads and fittings. Contains Teflon and is an alternative to organic lanolin and more appropriate for weathered high-loads than Boeshield T9.

I saw a guy at the yard slather it on his prop blades this spring :laugh:It is very sticky...

I would use a grease such as Super Lube for rigging screws and not oil. Washes away too easily.
Remember that 'Rigging Screw Oil' is an actual product developed by Selden Spars specifically for lubricating (their) rigging screws. When it was more commonly available, it was almost impossible to find a pro rigger without a bottle in his kit.

Many of the other product here can do this along with other admirable qualities that do not necessarily apply to rigging screws.
