I got these transparent covers for my Mac: https://cdn.shopify.com/s/files/1/0009/5354/8852/products/cm...
Then I made a custom vinyl skin from DecalGirl that was applied to the top transparent cover : https://www.decalgirl.com/skins/laptops/apple
Problem solved. Now I have a laptop "wrap" that isn't permanently or semi-permanently attached to the machine.
DecalGirl has a bunch of other laptop skins as well for Dell, HP, Acer etc: https://www.decalgirl.com/skins/laptops
