Good of you folks to commiserate (sp) with me, and to provide some suggestions. We're now in the BVIs, and still scraping the props from time to time. No big deal down here, and I'm not complaining. Just came back from Foxy's, where we had some bushwackers. And... they have wireless, which we are now enjoying.
A comment about the plastic bags. They might work, but plastic is sometimes mistaken by the turtles for jelly-fish, one of their favourite foods; and it can kill them. Better the turtles live, and eat those jelly fish
I can't imagine anything more tenacious than that lanolin, short of tar, so I wouldn't bother with greases.
I might try a tin-based paint
, next time I'm out of the water
, but the problem is the quick-oxidizing brass interferes with the adhesion. Anyway, for now, I'll keep scraping. The hell here never ends!! ;-)
