probably cheaper, quicker and less messing about to just buy a replacement section
I had a section of my superlite roll into the road
I wasn't funny
I was on the roof of the building, one of my guys was working below, I heard the section hit the ground, then heard a car horn followed by a crunch.
I knew straight away what it was. I was gutted.
On the bright side it was one of the final sections so I saved the top half. sealed the break and now have a very useful half section.
