Practical advice for scale model builders
PETG (Polyethylene Terephthalate Glycol) sheets are often marketed as a flexible alternative to acrylic or styrene, but they can be too prone to warping and shrinkage for scale modeling purposes. Consider using HIPS (High-Impact Polystyrene) or ABS (Acrylonitrile Butadiene Styrene) sheets instead, like those from Plastruct or Evergreen.
When working with scale models, a strong and flexible adhesive is essential. Tamiya's Extra Thin Cement is a popular choice among scale modelers due to its ability to bond with a wide range of plastics without leaving residue or bubbles.
Applying a primer before painting can significantly improve the adhesion and durability of your finish. Use a high-quality primer like Alclad II or Vallejo's Plastic Primer to ensure a strong bond between the plastic and paint.
When sourcing materials for your scale models, it's essential to know your suppliers. Companies like Plastruct and Evergreen offer a wide range of plastics sheets and rod, while specialty stores like HobbyTown or Michaels may carry a selection of scale modeling supplies.
To prevent plastic sheets from warping or bending, store them away from direct sunlight and heat sources. Use a stiff cardboard or foam core to support the sheets, and wrap them in plastic or aluminum foil to protect them from dust and scratches.
