TOO HOT will warp your back case causing your stylus to fall out or just dumb stuff like it won't go on right.. yeah just read first intro to this thread it goes into instructions... and don't leave flame on the whole time.. on and off every 4-5 min... that's what i did... i also read somewhere you can do it in the microwave so check into that one too.. may be easier to view what color your trying to get to... ;)
I just did it in a microwave and used a Styrofoam cup to get the water to the temp I needed, the cup was tall enough that the whole back door was submerged under the water. I believe this is the way dashy does it now too...
