Removable Cement to Fasten a Template to Aluminum

[jefelectric]

I made a cad drawing of the small control panel for my grandsons HO layout. What is a good removable cement to fasten it to an aluminum panel that will not stain the aluminum. I thought of using good old fashioned rubber cement, but not sure if it will stain the aluminum or not. Anybody out there with experience in this sort of thing?

Thanks for any help.
