Fixing a leak on the seams

[happybob91]

Hey all I recently went to a lake in Utah with high hopes, but found out my tube had a leak[:/]. I found out just barely the leak is on the seam, and everything I've read seems to indicate that is a hard leak to fix....I have a u-boat 2000, and am hoping to use it next week. I'm aware that I may be able to get it replaced, but I want to hopefully go next week. How have you guys fixed seams, if that is possible?
