AMMO by MIG Accessories - Glues for Modelling
Item: Medium Density Cement. Slow Dry

From the Manufacturer:

Medium density and high strength cement for use in assembling plastic scale models. It is particularly useful for gluing large components that need a strong initial bond. Clean the contact surfaces before applying the product. This cement will allow you to move and adjust the parts for a few seconds before it starts to harden. Dries completely in one hour and leaves no residue. This adhesive can be easily sanded and reworked once fully cured.
