I think you will find that it was "Liquid Paper" rather than "Tipp-ex" which was made on a kitchen table: http://en.wikipedia.org/wiki/Liquid_Paper
but it also took her 17 years to make a profit - so not a great example of "making a mint" from a kitchen table product. I don't know how quickly or easily she came up with the idea either. Presumably other people had used household paint to cover mistakes previously?
I'm not trying to knock you - if you have a great new magic formula then good on you, and I hope you manage to exploit it commercially. But I'm a little sceptical that you will suddenly be able to invent a new product that sticks to gel-coat (at speed), and prevents adhesion of weed, barnacles etc, doesn't wear off when you do put her on a trailer or a beach. Complies with the appropriate legislation on biocides. Is easy (and relatively safe to apply), has an adequate shelf life for production in any sensible volume etc. All this and compete with a number of well established players in a relatively conservative market.
So:- a homemade antifouling that works for you - maybe (although if I had made the investment you had I would stick to conventional off the shelf products). But make "a mint" I doubt it - happy for you to prove me wrong.
