HAAAAAAUUUL OUT MONDAY!
Hard to control myself...
As previously mentioned, we have a 2-blade classic Max prop. The first year we hauled out we didn't know what to do to it so we buffed it, cleaned it and put it back in the water.
It grew barnacles. A whole crop of them.
Last year we painted the prop with Pettit's Barnacle Barrier (safe for the prop metal and our aluminum sail drive) and this year we had two baby barnacles.
The other thing that we appreciate about this stuff is that it when we haul out we can scrub the remaining paint with a scotch brite pad and it comes right off...allowing us to respray without sanding or buffing. Hours of annoying work we have reclaimed.
This is what the prop looks like when sanded and buffed but not yet re-painted - from a neighbors boat. Pretty without paint, huh? Not so pretty when it grows a beard though so this owner also painted his with traditional bottom paint.
