I experienced the same nightmare. Maybe because my coach spent a lot of time in sunlight and high humidity areas, I dunno, but my Clear Bra started cracking and crazing in about 4 years. Then came the mold in the tiny cracks. My bra was left on way too long, because I tried to get it off, about 5 years after it was installed (installed 2004) when it started cracking and crazing badly. Labor intensive! So over the years I would try working on it a little bit at a time. And yes, I did try using the 3M Eraser wheel, plastic razor blades (even metal blades), solvents, heat guns, steamers, etc ... very frustrating. But ... Thanks Diplomat Dan! Dan's advice, from a previous older post on irv2.com of "Problems with 3m bra." Finally ended my Clear Bra Removal Nightmare, by using a 3000psi Water Pressure Washer. Viewable video at:
