The glue of the 5A quality octagon(rhinestud) and 4A quality octagon(rhinestud).
Ask: What is the difference of glue color for 5A and 4A quality Octagon(rhinestud)?
Answer: It is all about the material cost.
For the 5A quality, it adopts the better glue powder, while 4A uses the cheaper.
Moreover, there are a public secret, it is that 5A quality has a layer of clear painting between melted glue and aluminum plate, however, the 4A does not have this, so the 5A quality will have a better and stronger glue.
Actually the biggest difference between 5A and 4A is still the plating technique, not the glue problem.
