Make sure your models look their best before painting with these filler putties. A longtime favorite with aviation, military, figure and automobile modelers. Squadron Green and White Filler Putty is ideal for railroad models as well. Designed to quickly and easily fill gaps between plastic or metal parts, or repair surface scratches and nicks, the putty is fine grained (especially nice for small scale models) and quick drying. Just apply, allow to dry for 30 minutes, then sand to final shape. Each tube includes 2-1/2oz of putty, enough for several projects. Two different colors are offered to provide a suitable contrast on your model. This makes it easier to sand just the areas that need to be filled without removing surrounding detail. Choose from white, which is somewhat finer, for light-colored kits, or green for dark-colored kits.
