It peels off. I would recommend using a little soapy water on a sponge to ease the removal process. It definitely will not hurt the finish.
Regarding the application process, I watched the wrapsol video but would like to add that it is a good idea to wipe down the skins with a clean slightly damp microfiber cloth. My sheets had little pieces of dust and cardboard from the packaging. So wipe them off before you lift them off the sheet. I used a piece of scotch tape to remove the pieces. And I didn't use the included spray solution, instead i made a mix of dishwashing soap and water in a larger spray bottle which was a lot easier to spray with one hand.
What else- i wrap the squeegee in a microfiber cloth so that i don't create scratches (more imp. to do on zagg). Don't use too much pressure or else you will stretch the material too much. Keep an absorbent microfiber cloth handy at the edges to catch the excess water as you squeegee so that you catch the water before it starts running into vents or the joints. Oh, and I put scotch tape over all the ports.
