Hi David,
How many boat owners do you know that have had problems with paint etc? This is often the problem, 'general' information may not be applicable to your particular build/material/application.
I am happy to discuss individual requests via e-mail or via this forum, but it must be understood that this is relevant only to the particular boat and owner.
If general information is required on paints/coatings for both above and below the waterline then we would be very interested in providing this, presuming the forum owners are in agreement that it is appropriate.
