I'm in the middle of replacing the drive shaft , c clip , bellows , PTO bearing , etc... ---and in the manual they say to protect the drive shaft to spray it with P/N 219 700 304 and let it dry for 2 hours -- went to the dealer and they don't have any ( the kid didn't know what it was ) -- i can't find it on the OEM parts list on this site --- does anyone know what it is and where can i get some ? or something equal to it -- thanks for any help
