Artillery Fungus

I brought this subject up before under "Mysterious Black Spots". These spots are called Artillery Fungus which is spores from decaying wood chips. These spores are repelled about 20' and attracted to anything that reflects the sunlight. My boat is covered with these spots. Refer to: http://plantclinic.cornell.edu/FactShee ... fungus.htm

In this article it states that these spots are vertually impossible to remove. I can give definite proof of that. I've tried everything that I can think of and everything that's been suggested. I have a cabinet full of failed products.

I had a surveyor come in and look at the boat. End result is he suggested a complete boat wet sanding and buffing. This is serious stuff so keep you wood chips away from your boat, car, rv or house. The chips I have are oak and pine which were shredded into the woods when they cleared my lot and next to where I later stored the boat.

I hope nobody has to go through this. It's heartbreaking to see your boat with thousands of these spots and no easy solution.

Take Care,
Dick
 
I am sorry to hear you've had no luck so far on those spots. I know it sounds crazy, but there is a soap that dissolves organic stains gently and easily. "The Master's Soap" is a green bar (about $3.50) sold to artists to clean paint off their brushes, hands, clothes, furniture, etc.. It is amazing that something so mild can remove hard set oil paint with no irritation nor damage.

If you have not tried this, I would advise it. You can get it at Michael's art supplies or Hobby Lobby in the fine arts solvents area, etc..

You might try using a small fingernail brush to work the suds over the spots. Worth a try, I think. John
 
'Still trying to figure out something to help with those 'dots'...

As a dentist we use peroxide alot - the over the counter, 3% Peroxide to remove blood and debride injuries, and the much more powerful, 30% Superoxyl (a brand name of 30% peroxide) to bleach the inside of dark stained, 'dead' teeth. You'd probably have to get the superoxyl, 30% from a druggist or specialty house, and definitely want to avoid getting it on your skin, eyes, etc..

An immediate bleaching technique with the 30% hydrogen peroxide would be to warm the surface as much as possible without damaging the fiberglass, then hold a Q-tip (after having been dipped in the peroxide) to the stain, then touch the soaked Q-tip with a small, hot item, maybe a soldering gun, or heated tiny spoon.

"Walking bleaching" involves placing the peroxide soaked guaze or cotton onto the stain and holding it in place for several weeks. Maybe a suction cup might hold the peroxide on the stain?

Well, just some thoughts of possible answers. Good Luck, John
