Flash is excess material on a resin, plastic or vinyl kit. Sometimes, flash is the result of a sloppy casting job, or a damaged mold. It can also manifest as a Mold Line, which is the area where the two parts of a two-part mold come together and a tiny bit tends to squeeze out. Kits that come on a sprue will also tend to have flash on the areas where they are cut from the sprue.
Leaving flash on a statue, especially painting over it, gives it an unprofessional look. Priming a statue for painting will make the flash look exceptionally obvious. Thus, removing flash becomes a necessary step to those who want the best possible looking piece.
There are many ways to remove flash from a sculpt:
- X-Acto Knife
- Cutting Pliers
Which of these tools to use depends on the toughness of the material, the size of the kit, and the size of the piece of flash itself. Care must be exercised to not damage the actual statue material.
