Does the nano-coating affect the panel’s color options, metallic finish, or machinability (e.g., bending, grooving)?

A: No, it does not. The nano-coating is an ultra-thin, transparent protective layer (micron-level) applied as the top coat. It perfectly preserves all the colors, metallic finishes, or patterns of the underlying primer and paint layers. It also does not affect the physical machinability of the panel; you can cut, bend, and groove it just like a standard ACP.
