Hi - Selden recommends "Furlin' Grease PN: 312-501" to grease the in mast furler on my Hunter 320. What type of grease is this?? Would any grease do the job?? I'm concerned about using the wrong type of grease and it degrading plastic/nylon parts. I'm not even sure if there are any plastic or nylon parts on the furler. I was thinking of using White Lithium Grease.Any help specifying the type of grease would be helpful Thanks - Joe
