You may have trouble getting into the paint shed anywhere at this late date. We used Old Lyme Marina, in Old Lyme CT for ours. It's just up the Connecticut River, so it's pretty much on your way towards New York City. http://www.oldlymemarina.com/
They did an excellent job. Tell Mark that Eclipse says hello from Southport. We also checked out Essex Boat Works (in Essex) and Brewer's in Westbrook. They are bigger, and so it might be easier to work out a schedule with them.
