Sailcare running up the tab?
I had the same experience. 200 turned into 600plus shipping. I let them do it and was very impressed with the cleaning job. BUT, I would never let them do repair work again. Nothing with a sewing machine. Terrible work at very high price. Have repair work done before you send it. I had to have it all redone. They even sewed my baton pockets shut "repairing" them. But these problems did come back on a surprisingly clean sail. Would never do it on a newer sail, but if you just don't want to look bad it works
