Years ago I bought a tube of June Taylor's Fray Block and every thing I used it on had little white globs since instead of drying clear it dried white which of course it is not supposed to do. Well they reimbursed me the fray check with another bottle and also let me pick from there products to reimburse for the ruined projects. I would suggest that you go ahead and take them up on there offer and very sorry to hear of your experience. The reason my fray block turned white it had frozen in transport and then thawed and so that is why it turned white. A lot of us use the fusible batting all the time and unfortunately you got some bad product don't give up. Try the Un Do you may be very surprised by the results. Also they said they would pay for dry cleaning so take them up on that and see if it works. Good luck.
