On a recent canoe trip my seal on my dry bag tore. Is there an inexpensive way to repair this, such as finding some reinforced rubber strips and securely glueing to the bag? Or is this really not worth the effort and I should just spend the $60 on a new bag? Other than the seal, the bag is in great condition and does its job well.

This is a Eureka 40L, about a $50 - $60 CAD value.
