How do you handle doing mirrors that are so rounded, its like trying to wrap a piece of paper around a ball without getting any creases in it?
Start on one end and squeegee down one small area on one end and slightly heat this small area with a hair drier to lock it in place. Carefully lift the rest of the piece to the point to where it is adhered and reapply your mounting solution. Stretch the material across to the other side till crease fingers minimize. While holding this in place, briefly heat again to lock this second side into place. Now squeegee out all remaining areas and finish stubborn areas with heat to seal all edges. Mild heat and stretching are the key words here.
