Best adhesive to fix a model for long term display? What is the best adhesive to make a model into a permanent display like into a Christmas decoration or an ornament? I want for this model to withstand being packed and unpacked year after year.
I would suggest standard Elmer's glue (also referred to as school glue). It won't harm your LEGO so you can later remove the glue if you need to, but it is strong enough to keep a set together under normal use.
