I like it
I have it on my 60 and 100 and can say that it holds up very good. I put a coat on every fall and there is still plenty left next year. Yes this is overkill but in Cleveland you need it with all of the salt. I use an old POS Wagner paint sprayer that will never see anything but fluid film. Buy it by the gallon and spray it. I do have some of the small cans you can get them from John Deere dealers.
HTH
I Hava a Wagner paint sprayer and applied it to the bottom of my fj40 today. WIll see how it holds up
