Problem with a glue and the main reason most advanced modelers do not rely on it is that it is nothing more than a substance to stick two pieces together. The two mated surfaces never touch because of the medium (glue) keeps them apart.
Solvents penetrate and weld the two parts together. Forming a connection that is solid. Whereas, the glue forms a bond with minimal penetration if any. That is why the models I build as a kid can be easily disassembled the "bond" has broken down "dried out" and the parts are easily separated. Parts "welded" with solvent is similar to welding two pieces of steel together the seam is actually in many cases stronger than the surrounding surfaces.
Trying to apply glue to two separate surfaces then match them together is fruitless IMO because the bond and strength isn't sufficient, especially when you are building a hefty model like a B-52 in 1:72. The solvent route, is stronger and if done right can and will eliminate most of the seam issues one would have to go back and fill later.
Again as we mature as modelers and increase our skill levels, we've gotten smarter and found better techniques to solve our most serious problems. The basic principles of modeling are usually those that cause us the greatest problems in our builds...failure to do the basics correctly yields poor results in the end. It is all about the preparation or the process before the next that sets the stage for each sequencial ones success or failure. A string of errors usually results in a disasterous end.
