Hmm, what, the acetone evaporates and leaves just the plastic? Is that how it works?

And typically penetrates into the material (https://rhadhesives.com/why-chose-solvent-based-adhesives/ https://rhadhesives.com/why-chose-solvent-based-adhesives/). Adhesives are a deep and interesting subject if you're looking for a wikipedia hole. For example, if you want the best general-purpose consumer structural adhesive, it's Loctite PL Premium MAX. For the best general-purpose consumer structural adhesive applied in wide temperature ranges, it's Liquid Nails Fuze-It MAX. If you want the best flexible general-purpose consumer structural adhesive, it's Gorilla Heavy Duty Construction Adhesive. For the best all-purpose consumer structural adhesive when properly prepared, applied and cured, it's epoxy resin. For the strongest general-purpose adhesive when tightly fitted and clamped between two porous materials, it's cross-linked PVA (wood glue). There are dozens of variables that change which adhesive is better per application.

    They seem to have figured out some general purpose ones like B-7000 though. But yeah, agree on specialty stuff.

    > 3M Since it hasn’t been mentioned in this thread: 3M 94 primer with 3M VHB tape is truly amazing stuff for bonding things with high surface energy.

      high surface energy? mahm/father I yearn for the spicy surface

Yeah, the great part is you can then use fresh acetone to dissolve it. We do it with fossils all the time: glue it together, thin coat of glue all over then wrap and transport. Comes off easy in the lab.
