Can you seal the ends of the 10 ft. Royal Brown Aluminum Gutter Apron?

We suggest not to seal the butt ends of the gutter apron together.

We suggest not to seal the butt ends of the gutter apron together and to use a 1 ½” overlap. Sealing of the seam will prevent the flashing from the natural expansion and contraction with temperature changes and may cause an unsightly wavy appearance of the edging.
