The entire board was painted with Petit Trinidad bottom paint, but segments had different additives including cayenne pepper, litium grease, mercuric oxide, additional cupric oxide, and various other materials such as insecticides, etc. ,- I don't recall them all; however, I do recall the results. Only two of the additives had a lesser density of barnacle and other growth than the Petit Trinidad control panel. The mercuric oxide panel was almost completely absent of any growth and the litium grease coated panel had little growth. Certainly the mercuric oxide would be unethical to use as well as illegal and the grease coat of any kind would be less likely to adhere with an operating vessel.

I have often thought that I could coat my prop with something like this by adding it to a wax while melted and paint it on hot, letting it cool to a solid.

Which is the "something like this"? The HgO is a dangerous toxin that has been very harmful to organisms including people. Read about the "Minimata disaster". It has no use unless it is applied with the purpose of leaching into the environment and illegal for just cause. If you're speaking of the grease coating; then, the process of making it a hard solid would eliminate the feature that prevented barnacles from adhering.

Re: Bottom Paint Bio Additive

Actually I was thinking about the Seahawk additive..."Bio Boost" if it's legal for bottom paint.

My previous comment indicating that the "Bio-Boost" additive was TbT was incorrect. While SeaHawk does (or did) market a TbT additive, Bio-Boost is based on the aforementioned zinc omadine. However, the tech sheet for this product indicates that using it in conjunction with anything other a few SeaHawk anti fouling paints may result in paint failure:

Adding Bio-Boost to any other antifouling other than listed above may cause instability and result in unusable product.

Ya. Hilarious how non-sailing marketing fools have said things like "Bio-Boost". I am sure the bio material on my bottom does not need a boost or any other kind of help. That sounds like a fertilizer. What dopes.

thanks for that. What I read from them is..."Designed ONLY for Sea Hawk bottom paints". Sounds more like marketing to me.

Re: Bottom Paint Bio Additive

The Seahawk Bioboost, from what I understand, is for slime/algae protection....not additional help for barnacles/mussels. It works with SeaHawk paints that are solvent based...not water based. Good results are seen with there Tropikote or Biocop TF when adding Bioboost. No need for additive if slime isn't a problem.

Wouldn't it stand to reason the Bio-boost would work with other solvent based bottom paints, like Pettet Trinidad?
