The resistance is too high. You will need a total resistance of about 1 ohm for the whole grid. That material has 250 ohms per square. If a line of that material on the glass was 1 mm wide and 1 mm long you get 250 ohms already without making it any longer. With it that short the resistance is too high already.

Yeah, it'll make the rear glass melt right out of the frame.

Ah ok... bummer...comes in a rattle can too would've been plenty . Thanks for the reply
