Ahoy, I have a new 2002 Hunter 260 purchased at the end of 2003. The boat has only been in a lake for 9 months. On the hard I wanted to have the bottom painted. the Marina want's to lightly sand the hull before painting. Hunter says thet sanding will void the 5 year hull warranty. I have checked the achives, lot's about painting, nothing on sanding. Someone, Please throw me a line...
