I've been using Pettit Black Widow on my props and shafts. They now sell it with a primer as their "Running Gear
Guardian" kit, so I guess they also decided it was good for that use. It's a pretty slippery hard paint, but unlike something like Propspeed, it has antifouling properties rather than relying only on being slippery.
I'll know on Tuesday what my props look like after this season. Last year, after 6 months in fresh water
, I had no zebra mussels on any of the running gear
, no vegetation, none of those weird growths I see on a lot of boats around here. Just a light coat of slime on the shafts, rudders, struts, and trim tabs (wiped right off with a bare finger). Props were completely clean to the touch.
The first year, I had a few spots that didn't adhere great, so this year, I stripped everything back down and used Primocon instead of the Pettit zinc primer. We'll see if that helps the situation. The paint held up great wear-wise though, the brush marks that I didn't polish out fully were still there on the prop tips, etc. Basically no detectable wear at all.
