yes unfortuatly this is the only other way it can be done, we have stitched the two panels together and will grind the seam line back in, and then the seam will be filled up with a seam sealant that sets rock hard. it was either this way or a whole interior out job. and its only having part of the side cill repaired so not so bad really. if it was all the way along i would have removed the whole thing along with interior. but no need too this way.
