I spent most of yesterday trying to repair cracks in the plastic right behind the lid of the storage box on my '99 Coleman Nevada before the rain started today. Well I just checked it and apparently I didn't do a good job. Still leaking. Any ideas what I can do while it's wet to at least mitigate the leaks? It's supposed to rain the next several days here. I've never done anything like this before, so I'm sure I didn't use the best solution (fiber tape mostly). Help!
