i have a 03 Coleman bayside elite that is in excellent shape but my inside seam tape keeps flacking off. I've spent several hours trying to remove the old tape but only managed to remove about a foot. I tried using a ruff sponges, scrubbing brush, putty knife but the only thing that seems to work is my fingernail. Is there a easy way to remove the residue from the old tape? I also read from another forum that the tape was put in there for sewing purposes during the assembly and the tape does actually nothing for the canvas. When I manage to remove all the old tape should I put seam glue wheee the tape was?
