I'm at the point of back riveting my stiffeners to the .016" elevator skins and I read of a lot of issues with cracks propagating from the last rivet hole at either end but most often the trailing edge end. I will be following all the usual recommendations; proper bend radius, glob of RTV. I plan on doing the proseal mod too but I'm wondering if those who have gone this route would recommend doing the entire length of the stiffener or just the ends, maybe an inch or so? Seems like it could be unnecessarily messy to do the whole length and add time/weight.
