I have a very tasty pentex jib
which has lasted well , but upon removing it ,yesterday , I inspected it closely , and found a number of "cracks " in it , which if left , will rip . the sail is kevlar re inforced mylar laminate . Is there anything I can do to strengthen these weak areas , I have looked at spinnaker repair
tape , which is very good ,in my experience , but think that it will not be tough enough for this job .
