So I am finding out with this weather that my bike's cover is not waterproof....or even that close. I know that you don't want a bike cover truly waterproof due to humidity issues, but how much water resistance can I/should I expect? Are there waterproofers that I can reapply to the cover, or just get a new one, or in constant rain am I just looking at the bike being wet under the cover? Sadly right now garage isn't an option. Thanks guys.
