[QUOTE="Rat, post: 110143, member: 1914"] Looks like shear forces cracked the steelflex. Most likely you have a rivet hole that is elongated, or wallowed out somewhat, causing the rivet to move along the x axis, cracking the steelflex around the head. Because it is in the hull bottom and through the lateral rib, and knowing that you have rebucked it, it is proly the panel with the elongated hole and the rib hole is the right size (the rib being the thicker of the two), causing the barrel of the rivet to expand to the hole size of the rib, but not the panel, thus allowing it to move enough to crack the steelfelx. The hull panel is moving enough to cause the rivet to move. This is just a guess based on what I see and what you have said. It may be as easy as drilling the hole out to the next size rivet and installing a bigger rivet. That's what I would do first before trying to patch it with 5200 or something similar. [/QUOTE]
