Welcome to the newest innovation in modeling. Weathering Solutions™ decals offer an easy, unique, cost-effective way to achieve an authentic look on any model, by modelers of any skill level. Follow these simple instructions and bring your models to life.

TIP: Referencing prototype photos will help you to select and optimally place decals on your model. Visit for a gallery of our favorites.

  1. Begin by washing the model with mild soapy water. This will remove any surface contaminates and yield a fresh clean surface.
  2. Apply an oil wash. This is crucial for an all-around weathered look. Consider the following when choosing an appropriate oil wash color: car type, commodity hauled, car age, damage from loading/unloading, etc. An excellent choice for beginners is Van Dyke Brown which is a neutral, grimy shade. Start with a small amount of oil color and turpentine or turpenoid® and apply over entire model. Immediately after applying, take a flat, dry brush and pull excess oil from top to bottom in vertical strokes. Blot the brush on a clean cloth between strokes to remove excess. Repeat this step as necessary to achieve desired color. Allow the oil to dry fully before proceeding. Drying times will vary, but typically 48 hours is sufficient.
  3. Apply a clear coat and allow it to dry for about 2 hours. The desired end result is a glossy finish without imperfections. There are two methods that work equally well:
    • Pledge® FloorCare Multi-Surface Finish (says “acrylic” on the back) with an airbrush, or
    • Gloss enamel clear coat in an aerosol
  4. Prepare the decals. Images on the decal sheet are arranged to maximize value. Use caution when cutting out images you intend to use and set them aside in the order in which they will be applied. Use hobby tweezers to place one decal in a saucer of warm water. The decal film will release from the backing after about 30 seconds.
  5. Recommended Step: Apply a thin layer of decal setting solution, such as Micro Set, to the model’s surface just prior to placement of the decal. This step minimizes the possibility of air bubbles, ensures the decal film bonds securely, and softens the film to allow easier molding to raised surfaces such as rivets, seams, safety appliances, etc.
  6. Apply the decals. Carefully pluck the decal film from the water and move it into place with the bottom side contacting first and lightly dragging the film upwards to “land” it in the desired location. Take a cotton swab and gently roll off excess water.
  7. Use care not to shift or wrinkle the decal. If air bubbles occur, simply puncture them with a sharp hobby knife and apply a tiny amount of Micro Set over the area. After you are comfortable with the process, repeat step 5 and 6 until all decals are applied.
  8. Recommended Step: Apply a thin layer of Micro Sol decal solution to “melt” the decal into the painted surface. This step reduces the visibility of cut lines, improves continuity of overlapping decals, and further softens the decal to conform to the surface. Allow the model to completely dry.
  9. Repeat step 3. This will ensure the decals do not stand out from the surrounding area.
  10. The final step is to apply a dull-coat. This is necessary to remove the gloss and shine from the film and clear-coated areas, as well as to provide a layer of protection over the decals. The best product for this is Testors® Dullcote.
