Most adhesive pastes are going to be some form of filled and toughened epoxy. The adhesive bead diameter is usually tested on many samples to see how much is needed to ensure a good bond with minimal squeezed out, and how much pressure to apply via clamping or vacuum bag. And aircraft production lines are going to use that specified amount of adhesive. Generally, blind adhesion joints are disliked by both engineers, manufacturing, and QC staff. But there aren't many ways to effectively eliminate them. So they place them non-critical or less critical areas. E.g. lower wing skin to spar and ribs, where air pressure at maximum loading is positive, not on upper skins to spar. Where air pressure is negative and might rip the skin lose.

Sir, this is a Wendy's

@@Joaking91 Even so. Look at the technology that goes into building such places. Certainly, the technicians are the crafts people, but, many times, not always, it is the evil ones who own such places. Who should be running our world? Kind geniuses who are vegans. The fact that it is a meat frying market alone makes it evil.
