KCStudly - I think you're right. If the canvas is still pretty saturated and has a good grip on the foam, it will do the trick. It's going to be painted, afterall....
The stapler I used was something like this

rowerwet - filling the outer weave with primer/paint makes sense. I keep thinking "It must be saturated with glue!!" to keep it waterproof, but obviously paint and primer will do the trick.
All day i've been having visions of water gushing through the roof and wood rotting out on my first night in this thing.... Get outta my head, crazy ideas!
I'm starting to consider paint options. From what I've read on here, just about ANYTHING will work. I need something burly enough to stand up to 50,000 miles of driving, but I don't need/want a super smooth, fancy high gloss finish (or the hours and hours of sanding!!!!).Some texture would be pretty cool. I'm thinking about primer then rolling on automotive paint. I'd love to hear opinions, I'm clueless about this part!
