Got a small split in your leading edge/Struts or some pin prick holes you don't want to get worse and it's not big enough to warrant a professional repair?
Dr Tuba sticky backed Dacron is the answer. It is just that, dacron strip with a sticky acrylic adhesive back to it. Simply clean off the area with an alcohol wipe, for best results key it lightly with some fine sand paper too, cut a patch to the size you need, round off the corners and stick in place. A repair for small holes and pin pricks.
Perfect to keep in your kite bag to save a session and if used with Aquasure PU Glue you can repair bigger splits and tears too. The pack contains one roll of White Dacron tape 5cm wide by 300cm long plus an alcohol wipe.
