Haven't used prop speed, we use a spray anti foul that is sold for outdrives and outboards (WM and most other marine suppliers sell it, don't remember the name but it's very common). Two months ago I cleaned the bottom of the boat and expected the prop to have a lot of growth on it (two years in the water) but it only had two or three small barnacles, other than that it was clean. By comparison, I swam over to my brothers boat and the prop was completely fouled with hard growth to the point where the blades wouldn't turn on the Autoprop(I think it had been three years since haulout).
I clean the prop thoroughly and scuff with a pad and then use zinc chromate spray primer and then two coats of the antifoul spray. About $20 for a can. I've used it on our powerboat prop for years, this was the first time I'd applied it to the sailboat. We are in the PNW, cold water.
