I have a Serfiac gold with tip extension . It was a 2 piece , but now a 1 piece from corrosion. I have attempted to separate recently . Syringing vinegar at join. Penetrating oil . I never used with that sail though. The Serfiac is in Brampton . The sail is in PEI.
Got a handful of sails, 2 boards, 3 weeding, and a wetsuit, at different times over the past 6 years from 2 Rad. To SF Bay. Fast, courteous, good weekday communication, fair prices. Oh, and my 9'6" SUP.
