Has anyone tried simply rubbing marine grease on the prop every 2 - 3 months? I have been told that this works well for periods up to about 3 months. Haven’t tried it myself yet…

I tried PropSpeed 3 separate times. (They certainly are proud of that stuff!)
I had the same results as you. Very unsatisfactory. I tried everything, and finally found a decent solution.
I use the spray. About $35 US for a can.
I use the whole can on my underwater metal, usually 3 or 4 coats on the prop. I burnish the fully dried paint with a heavy duty scotch brite pad, to expose the zinc (not on the edges, but the flats of the blades).
In an entire season, not a single barnacle or growth of any kind on the prop. And the paint stayed adhered to my stainless prop. I don’t burnish the other underwater metals, and do have some growth on them, so the burnishing is important. I spray the prop once a year.
Looking for advice- I'm doing a bottom job in 6 weeks. Last year I used Propspeed on my Autoprop and 6 months later there was no evidence of it.....the barnacles however were flourishing. While I enjoy diving I like it better without a scraper in my hand. Given the cost of Propspeed, 6 months is unacceptable. Would love to know if there's something better out there.
