How difficult is it to remove the lettering / decal?
The decals will not come off till you want them off 🙂 But when you do, they come off easily.
On glass, very easy. Simply slide a razor blade under the decal. Once removed any glue can be removed with glass cleaner. On painted surfaces a little bit more work. Pick and pick and pick with your finger nail. If in the sun it comes off better. But it does come off with no damage to the paint. Remove the glue with mineral spirits.
