M & K 8 Inch Subwoofer Foam Speaker Repair Kit FSK-8-1 (SINGLE)

I use this successfully to repair a blown out woofer. With CARE it can be done. But follow the directions carefully in well ventilated room. Needs focus and attentive work. In the end though, the speaker got repaired and everything got cleaned up. Should I need to do this again, I'll be more careful! Process was messy, but it was my fault, not the products. Get all set up before starting.
