Quoted from ForceFlow:I might be tempted to try to cut that area out carefully with an xacto knife along the black lines, use a mylar removal technique (either heat or cold), clean & wax the exposed area, then put a patch of mylar down. Maybe one that fits inside the area that was cut out, and another larger patch on top of the patch to cover the edges/seams.
UH yeah, don't do that unless you want your game FUBAR! You would essentially be cutting into wood. I used the freeze method and had no issues
