Abstract
A weatherproof decal employs an adhesive coating to hold the lettering or the like to a smooth surface. The adhesive coating covers the lettering and the spaces between the lettering. A further adhesive layer employing the same adhesive agent is present only in the area of the lettering in direct contact with the adhesive coating. The adhesive layer has an adhesive strength larger than that of the coating which holds the lettering. The adhesive strength is controlled by admixing talcum and a mineral oil to the adhesive agent.
