I'm trying to stir up new business and want to add some signage to my van. I'm interested in your thoughts of the pros and cons of both the magnets vs the decals. Have you received any business by having them on your vehicle? Do the magnets need to be removed often to clean? Can they go through the car wash? Are the decals permanent? Can decals go through the car wash? Have they ever come off while driving? Merrill vs Vista products -- are the qualities the same? Any thoughts and opinions are welcomed. Thank you!
