Does it have any effect if the powder is sprayed too thickly?

This will definitely have an impact. It depends on what type of spray you use. If it is sand-textured, it will cause orange peel. If it is flat, the surface of the product will wrinkle. If the pattern is too thick, it will cause wrinkles. The large flowers are too ugly and affect the appearance. However, compared to the patterned ones, the sanded ones can be painted later....
