Seems like if you just used it with the pressure of the clecos and allowed it to set up before riveting that the joints would not be as tight. Riveting certainly pulls the metal tighter than clecos.
John, it seems to be a common thread with RV building.
One builder does a task and it comes out looking beautiful, and another builder using the same parts and instructions can't get it to look good after even three try's.
All of the early prototype airplanes were built using no adhesive, so that is what went into the manual. After a while it was obvious that a certain % of builders had a hard time, so bonding first was added to the process, to help them get a better finish quality.
