The Arming Putty Classic from AMMO By Mig is a solvent based putty specially designed to cover joints and defects in scale models.
You can easily seal and eliminate any seals between parts by applying the putty using a spatula, to be later sanded smooth.
You can also dissolve the Arming Putty Classic using thinner, or extra thin cement for a stronger adhesive strength. This also allows the controlled application of the putty with a brush.
The Arming Putty Classic A.MIG-2040 does not contract or shrink when drying, unlike other putties, and dries to a hardness very similar to plastic which can be later sanded to a perfect level.
