==== Polystyrene Cement ====
Another cement. It will say "plastic solvent" or "Warning: solvent". This kind will melt plastics slightly, and is much more permanent. Should only be used for the harder plastics. 
Drying time varies by mixture. Precision is required for Polystyrene Cements since their nature to melt will result in ANY glue anywhere it shouldn't be leaving a nasty-looking mark that can be worse than any mold line. 

* "Thick Tube" versions, which as you may have guess come in a tube like toothpaste, are popular with scale modelers, and are what most people think of with Revell model kits. Thick Tube is the most powerful, and takes hours to even days to dry and can damage a model very badly if it gets anywhere but where you are applying two pieces together. 
* "Medium Viscous" come in bottles with extended applicators, and both dry faster and cause less damage if improperly handled. These are the most popular versions used today. 
* "Ultra-thin/Liquid Poly" come like paste, sitting in a wide bottle with a brush attached to the lid to use to apply with. The brushes can be cut to be thinner for more precision. Cause the least amount of melting, and dry almost instantly. The version stereotypically associated with [[Tamiya]] models.
