Antivegetativa piccante...

[ugo]

Cercando in rete si trovano informazioni interessanti.
segue una sintesi di un articolo preso da "Boating Writers International", "Bottom paints basics", D. Liscio, http://www.bwi.org/images/basics.pdf

...there are always those special kinds of boaters who ignore the latest formulas...in favor of old-fashioned concoctions they believe will keep hulls barnacle-free...

...For example, despite field tests to the contrary, a few diehards still slather diaper-rash creams... or they add cayenne pepper, chili powder or dried red-pepper flakes to their paint. Jim Seidel, assistant marketing manager at Interlux, says the industry has experimented with spices and other organic ingredients, all with negligible results.

... at Interlux they’ve concluded that nature’s hot stuff just doesn’t do the trick.
... Interlux also tested antifouling paints blended with jalapeno or habanero peppers. “The pepper blistered the guy’s fingers in the lab when he touched it, but we didn’t see a whole lot of difference in the paint.”

insomma sembrerebbe che anche i produttori di antivegetativa abbiano fatto delle prove, ma senza alcun risultato ( o meglio con il risultato di concludere che questo tipo di additivi non ha effetto sulla vegetazione).
