I applied it again yesterday after I washed and waxed my Liberty. Worked it into hard to reach places with an old house paint brush, and rags.
I started using it a few years ago after watching the oil filter cap screws starting to corrode so soon on my new Burgman.
At every stop, and while sitting nearby having my coffee this morning - I got to enjoy the smell of it cooking into all the places I applied it.
It is not a pleasant smell, but I like knowing what it's doing down there.
Some bikes, like my son's Honda 500X seem to be so well coated with paint or clear coat - that it doesn't seem as necessary on most of the bike.
I recommend the hand pump ('spray') bottles.
