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.
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.
