Someone told me about a "myth" that you could glue legos together with a solidifying hairspray like Tresemme stuff, or similar firm hairsprays (that ones that solidify your hair and dry out fast)
Id rather not test it on a random brick to know, but I have a few sets of rare limited edition model weapons (Like Actual Silver versions of lego ninjago weapons and other such common rares, but I also have some extremely rare things like the goldplated minifig katana)... And I keep losing the pieces to them (I usually find them but still!!) And Due that Im only using them for collection (not play) I dont need them to be seperatable.
Keep in mind, Im not really applying this question to my 1 piece rares or my metal minifigure items. I also have some old limited edition plastics that no longer "exist" and they tend to be weapons and pieces made from multiple small pieces.
Is something like hairspray a workable method (Ive heard its similar to those "bead glues" that you see on TV where you make plastic beads, and spray them with something and they stick together...
if this isnt a good method to go about with this, Perhaps a better method thats not expensive nor messy, but works well and looks good.
I plan on later getting an artist to line them up and put them in Epoxy resin, but for now I need a glue method (For bragging rights :3)
