I just went back and did it again with a little more tape. I let it cool for a while the first time but after a couple of hours one of the mags was sticking (slightly) again. Going to let it sit over night this time. I might not be boiling it long enough but I am a bit paranoid of damaging something .
I wonder what would be better, to heat and then cool naturally or heat and put in cold water to cool quickly? Any one now what would be best for a material like this to hold its shape?
