I've never used the grease, just cleaned the fuses every so often and
made sure the holder was tight (bend the ends together). For the 122,
there is a fix - involves removing the rivets, cleaning the brass
laminations and then soldering them together and replacing the rivets
with 6-32 screws and nuts. Have not had the need to try this on later
cars. Usually if the holder is tight, rolling the fuse 90° is enough.
