Which exterior casket finish involves a coating that wrinkles as it dries?

The crinkled finish is characterized by a coating that intentionally wrinkles as it dries, creating a distinctive texture. This effect occurs when the coating is applied and then allowed to dry in a manner that results in the formation of small, raised patterns or textures on the surface. The crinkled finish adds an artistic and unique element to the casket, setting it apart from more traditional finishes.

In contrast, the glossy finish provides a smooth, reflective surface, while the satin finish has a soft sheen that lies between matte and glossy. The matte finish is flat and non-reflective, lacking the characteristic texture that the crinkled finish exhibits. Thus, the crinkled finish stands out for its specific drying process that produces a wrinkled appearance, which is why it is the correct answer.
