LOL, it's been almost a year to the day that I posted this, how funny.
I doubt anyone's still paying attention, but I just thought I'd throw out an update.
I haven't done anything further with the roof, I've been keeping a very close eye on things and can't see any additional problems or areas of concern...the membrane still balloons up a bit at highway speeds, but we've been through some helle rainstorms lately and still no evidence of leaks I can find anywhere. At this point, I'm just going to maintain the status quo and hope to get another year or two out of the roof. Once I detect the slightest hint of water penetration, I'm tearing off the whole roof and having it done with the Rhino Eco Liner...seems to be the best option. Anyone done this roof before?
