Coat prop with Lanolin for antifouling?

[geoleo]

Anyone here done it or know about it? Can it be done in water over Trinadad?

I have used Lanocote Prop and Bottom which is lanolin based. In actual use it lasts about 3 months. I had a friend whose boat sat idle for two years and had no growth on the prop with the product. The product can be used under water but I have only had success in warm Florida water while in Maine it wouldn't stick to the prop. Also the metal of the prop has to be extremely clean before applying. If there is any growth or slime on the prop at all it won't stick. We use a scotchbrite pad to get it clean before attempting to apply it in the water followed by wiping with a cloth just before applying. I find it is much easier to apply out of the water. If the water is full of particulates you may have to apply the Lanocote immediately behind the cleaning cloth. I cannot tell you how plain lanolin would work, but the Lanocote product seems to be a bit thicker than plain lanolin and even their anti-corrosion product for dissimilar metals.

Chill the lanolin to firm it up, then apply it like surfboard wax on a clean surface.
It works great as a preservative when the boat is sitting idle, but quickly washes away when the prop is actively spinning.

Garbage bag over the prop works too

I found that this product would not spread or readily stick in the chilly waters of San Francisco Bay

I applied it to a prop while the boat was on the hard. It's just hard to say how much good it did, but I think it helped slow growth.
Once I tried a whole can of silicone spray on the two props of my catamaran. Didn't help at all really. I was on the hard and the can was getting rusty so I tried it.

I tried Desitin once. The barnacles thrived on it.
