In the quest for a flawless finish, particularly when dealing with injection plastic models, hobbyists often encounter small gaps that need attention. One invaluable technique for addressing these imperfections is the creation and application of "Sprue Goo." This homemade filler, crafted from the very material you use to construct your models, proves to be a versatile and effective solution.

What is Sprue Goo? Sprue Goo is a modeling putty made by melting leftover plastic sprues in liquid cement. This mixture results in a gooey substance that can be used to fill gaps, seams, or imperfections on your miniature.

Crafting Sprue Goo: A Quick Guide

1. Collect Your Sprues: Gather leftover plastic sprues from your model kits. These can be from the same kit or similar plastic types.
2. Cut the Sprues into Small Pieces: Using hobby clippers, cut the plastic sprues into small, manageable pieces. The smaller the pieces, the faster and more evenly they will melt.
3. Prepare a Container: Use a disposable container that can withstand the heat of liquid cement. A small metal or glass container works well.
4. Add Liquid Cement: Place the sprue pieces into the container and pour a small amount of liquid cement over them. The liquid cement acts as a solvent, breaking down the plastic and creating a malleable substance.
5. Mix and Wait: Stir the mixture well with a disposable tool or a scrap piece of sprue. Allow the mixture to sit for a few hours, giving the plastic time to dissolve in the cement.

Applying Sprue Goo to Fill Gaps: A Step-by-Step Process

1. Prepare the Gap: Ensure the gap or imperfection on your miniature is clean and free of debris.
2. Apply Sprue Goo: Use a small tool or applicator to carefully apply the Sprue Goo into the gap. The goo should be pliable and easy to work with.
3. Smooth and Shape: Once applied, use a sculpting tool or the back of a hobby knife to shape and smooth the Sprue Goo, blending it seamlessly into the surrounding area.
4. Allow to Cure: Give the Sprue Goo sufficient time to cure and harden. The curing time may vary based on the specific liquid cement used, so refer to the product instructions for guidance.

Advantages of Sprue Goo:

• Cost-Effective: Utilizes leftover sprues, minimizing the need for additional materials.
• Customizable: Since Sprue Goo is made from the same plastic as your models, it bonds well and can be easily painted over.
• Environmentally Friendly: Repurposes plastic sprues that might otherwise be discarded.

By incorporating Sprue Goo into your repertoire of modeling techniques, you add a powerful tool to your arsenal for achieving a flawless integration of components, ensuring that your injection plastic miniatures stand out on the gaming table. Happy modeling!
