My '89 Coleman has Evolution III fabric. I've had the camper up in Camp Driveway for a week and today's very heavy storm revealed only a couple leaks in the fabric. I read somewhere that scotchguard should be used, and read elsewhere that scotchguard should NEVER be used. If anyone here has Evolution III, I'd really appreciate knowing what you've been successful at using to waterproof it. Thanks!
