My bike will outside without any shelter for another season once I bring it out of storage. I use a quality Nelson Rigg cover that is waterproof. It has a small tear that I'd like to repair if possible. I will be buying a bigger bike this year, so I don't want to spend the dollars to replace it, when I'll be getting a new and bigger one. Also, is there a way to treat it to make sure it remains waterproof? I've used it for 2 seasons so far. Thanks.
