I was looking through a build thread and saw that a guy had slathered sealant on the skin and the rib flange, then cleco'd in place. Allowed the sealant to set, and then riveted.
Now, when prepping sheet metal, we drill/ream/debur to get the best possible fit. Yet somewhere/somehow this interference layer of sealant is acceptable??
How can the rivet develop full shear strength with all this sealant? I would expect (and was taught) rivet, then seal.
What am I missing?
