Sailcare Experience
You need to understand what SailCare's process is: first they essentially dry clean the sail, which removes the old resin and anything else such as glued-on numbers, insignia, etc. Then they replace the resin, which makes the sail stiff and crinkly like a new sail. They can inspect the sail for wear and stitching problems, but it is very difficult for them to tell if the sail shapes well - that is your job. A year ago I had them do a main and a jib for me - the sails came back looking beautiful and are decent cruising sails, but have seen too much use to be effective for racing. SailCare told me 10 weeks (busy winter season) and they lived up to that schedule. Later I sent them a genoa for an estimate - they sent me the estimate, at which time I decided not to have the sail done, as it was not really worth putting that much into a sail I couldn't use on my boat (I intended to sell it.) I let some time pass before informing SailCare I had decided not to have the sail done. They told me that because it worked into their schedule they had already cleaned and treated the sail, but would not charge me since I had not OKed the deal. That indicated a real interest in customer satisfaction to me. Of course I went ahead and paid them for the work, as the mix-up was my fault. In short, if you have a good sail that is grimey, SailCare is a good way to get it looking good. If you have a blown out sail, have a sailmaker check to see if it can be recut before putting big cleaning bucks into it.
