When spraying paint, the spray gun should be moved in layers from top to bottom to ensure that excess water in the mold cavity can be blown out of the mold cavity. For cavity parts that are relatively sticky to the mold, it is possible to spray them at a close distance and then spray them at a long distance. After spraying, use air to blow off the excess paint inside the mold cavity to prevent air holes, blisters, and other conditions in the die Nneɛma a wɔde gu mu.
