I usually use a coat of spray paint. The color is unimportant. After etching, a little acetone or paint remover takes it all off.

I'm getting ready to etch a two sided PCB for a satellite related homebrew project. The bottom side is the ground plane which I don't want etched.
What is the easy way to protect it from the etching solution?
Electrical tape? Masking Tape? Sharpie Pen?
Thanks
