This is a 2.5″ x 4″ hard plastic squeegee that makes putting large decals on a lot easier. Used in conjunction with a 50/50 solution of distilled water and 100% alcohol. You can re-position the decals until you get them in the prefect spot. Then working from the middle out, push the fluid from under the decal. More detailed instructions on the “float on” method can be found here.
