1st time tent trailer owner. 1997 Coleman Niagara Between the ceiling & wall on both bunks of our newly purchased trailer a seam has popped open. Previous owners tried to use some kind of tape that has left a nasty stick residue on the canvas. I planned on using Loctite Vinyl, Fabric & Plastic flexible adhesive sparingly to put the seams back together then hand sew to ensure a good seal with some UV upholstery thread. I have tried to find something on here but couldn't. Is this sound thinking or is 1 of these a no-no?? You can see 1 of the seams in the attached pic. That one is the worst about 2' long.
