Benefits, uses, and practical tips

Working with hobby putty opens the door to cleaner builds and more ambitious projects. Here’s how to get the most out of each type:

• Smooth out seams on aircraft fuselages, tank hulls, or car bodies
  Gaps along assembly lines disappear completely with the right application and sanding sequence.

• Reshape details or rebuild lost edges
  Useful when sanding has softened panel lines or damaged corners that need restoration.

• Sculpt custom elements
  Epoxy putties let you build textures like cloth folds, armor plating, fur, stones, straps, or organic shapes.

• Strengthen or reinforce joints
  Some putties bond tightly to plastic and metal, adding durability to fragile areas.

• Achieve paint-ready surfaces
  Surfacers help level imperfections and give your model a flawless basecoat foundation.

Application tips from the pros:

• Moisten your tools for smoother application with acrylic putties.
• Use sculpting tools or silicone shapers for epoxy blends.
• For large conversions, apply in layers rather than all at once.
• Sand only after the product has fully cured—curing times vary between formulas.
• Combine putty with primers or surfacers for ultra-clean results before airbrushing.

With options from AMMO by MIG, The Army Painter, and other trusted brands, this collection ensures consistent, predictable performance. Whether you’re doing precision repair work or pushing into full custom sculpting, the right hobby putty makes a noticeable difference in quality and ease of execution.
