ThreadTheory SeamSure Fabric Repair Kit

To Whom It May Concern: After approximately twenty machine washes on a gentle cycle with cold water, the ThreadTheory SeamSure Fabric Repair Kit has performed its intended function with such thoroughness that it has now bonded the seam of my running shorts to the interior mesh lining in a manner that cannot be separated. The repair itself is flawless—no fraying, no lifting. However, the resulting stiffness has created chafing on my inner thigh during a 10K race. I purchased this to extend the life of my training gear, not to render it unwearable for long distances. Would you kindly advise on a solvent or method to reverse this adhesion without damaging the original fabric? I appreciate the durability, but it seems to have exceeded reasonable parameters.

Only had it one day and I fixed a tear in the elbow of my jacket after work. Wife walked in, saw the repair, and said 'You could be a tailor.' I said 'It's just a kit, love.' But honestly, it feels solid. I'm a school caretaker so I deal with busted seams on my overalls daily—this stuff sets up fast. Not messing about. She was impressed and that's a win in my book.

This is likely a fine product. The instructions are clear. The repair held for a week. I just woke up in a sour mood yesterday and decided I hated the color. No real issue with the product. One star because I felt like it.
