Design Sharpie

How do i Keep a Sharpie marker on my laptop?
I want to draw a design on my Laptop with Sharpie permanent markers and am wondering how i can do so without the design smearing at all, and i don’t want to try to draw a line and see if it does, and end up having a smeared mark. does anyone know what i can do?
I believe it will only smear if you touch it before it’s completely dry.
