Mailport November 2012 Issue

Mailport: November 2012

Prop Paint Feedback

I used Pettit Barnacle Barrier with similar results (PS Mailport, September 2012). After a month, there were 1/3-inches of barnacles on the bronze prop of my boat, which is kept in warm Raritan Bay in New Jersey. I scraped them off with a spatula. However, I donít think the Barnacle Barrier was applied properly. I put on three coats, but the last coat was about three weeks before going in the water. It should have gone on about an hour or so before splashing, and it should have been washed with fresh water just before going into salt.

I believe what happened was that the zinc oxidized and became ineffective. However, after cleaning the prop while in the water, which also removed the layer of oxidized zinc, it stayed clear until August, when a few barnacles appeared here and there, and easily cleared off. By late September, it was still fairly clean as well. Next time, I'll apply it as recommended. Hope springs eternal.

Thanks for the feedback. We have several ongoing field tests of prop paints. Stay tuned for the results in an upcoming issue.

I am promted to write by a recent reader comment justifiably critical of 12-volt receptacles. I have replaced mine with Powerlet-style connectors as found on BMW motorcycles: the quality of much better, they are weatherproof, and a wide variety of styles and functions are available. Try Whitehorse Gear for a listing.

I am wondering if the article in Nov. issue on fuel additives are for gasoline and diesel or are there different products for each type of fuel.

I must also add to my post on the Forspar Mini Galley that a friend has the same unit on his boat. He removes the propane canister every tome he stows the stove. He eventually tore the O ring inside the propane canister and threw the entire blazing stove overboard. I lubricate my O ring with spit before attaching it to the stove. The canister then stays attached until empty, reducing the possibility of causing a leak.
