Roof-top illuminated letters: How to maintain and care for the stainless steel parts?

The reason for paint peeling is primarily due to excessive humidity in the environment. It's fine to get rained on, but if the paint on the rooftop signs is constantly soaked, even the best paint can't withstand that.

Do not attempt to move while maintaining; moving the already installed rooftop illuminated letters may affect the power lines or lettering, potentially causing---.

Rooftop illuminated letters are frequently used and inevitably get dirty. It's important to use dry materials to clean off the debris.

What factors affect the power consumption of rooftop illuminated letters?

The area of the top-mounted illuminated letters is proportional to the light source density; the higher the light bulb density, the more power consumption.
