Hello Capt! Congratulations on the new boat, she's a beauty! IMy late husband and I spent a week on a Morgan sailboat in the Virgins. They are roomy but sail like a tub! Also got to tour the Morgan factory once, it was interesting. I did know that they made a few powerboats but have never seen one. All my life my family and I have been in the printing INK business and there are many similarities between inks and paints but rarely do they ever try to do each other's job! There is a good reason for that: both employ highly trained chemists to create their secret formulas for different purposes. These formulae are normally secret since they are created at great cost and the business is highly competitive. Trying to mess with them or add foreign matter can easily ruin a costly batch of paint and not work in any case. There is a tight balance involved in making that paint, or ink. It is highly technical! Another Listee suggested a kind of tin but I recall it was copper that was formulated into the paint, not dumped in. If you can afford copper, if you can even buy the type you'd need, you can easily afford a brand new boat with granite counter tops over teak cabinets! Just think what that would cost and still you'd end up ruining the paint base! All of us like to save money but often there are valid reasons for not doing it yourself! We DO agree that the government knows best in prohibiting the good stuff, don't we? Yes, TH Ey do make a paint to cover some plastic, Rustoleum, I believe...but not all plastics are the same...that old know what you're doing thing! Learn to love yellow instead!
