You'll have to calculate how many rolls to buy.
Special way to apply. Hook start end on aluminum frame. Then pull tight and cross over the panel then cut the tape so it adheres onto the other side of the panel.
You have to press STRAIGHT DOWN in dabs with something like the end of a 2x2 You should not wipe or rub.
This is some amazing film. It will not UV deteriorate or turn yellow.
You will end up with some bubbles. Bubbles pass more light than creases. No touchee.
Been there done that dept buying broken panels.
