Other than replace the top A friend of mine had a similar problem and used a bicycle tube repair kit (patches) and it seemed to do the trick.It's a low buck fix and maybe it would work for you. Or you could use some vinyl and some adhesive and go that route.Do you just want to keep it from getting larger and the inclement weather to stay out? Good luck. David.
