Reading up on it last night, preparing for when I do mine ;) it seems the seams are joined at right angles, then yes, clips are put on and these hold the seam covers on.
Seam covers are "about" $50 a pair so that's cheap. Also, the way it's set up, it should actually be a fairly easy fix. Cut it out, make up two new sections and weld them in.
Easy peasy :eek:
