Abstract: A masking system including a water soluble liquid masking composition to be spray-applied in film form to a limited area of a configured surface having a contiguous area to be coated for suppressing dust in the limited area and to prevent dust from migrating to and marring the quality of the coating, comprising an aliphatic polyhydroxy liquid carrier in which are dispersed a thickener and surfactant, the viscosity of the film being such that it remains substantially continuous on a vertical panel.

Abstract: Method of restricting a coating to a first area having an adjacent second area which is to be covered by a mask before the coating is applied, including the steps of separating the areas with a barrier strip of masking paper, applying a masking composition to the second area pressing the paper against the composition to produce a guarding edge between the first and second areas, and applying coating material to the first area, the masking composition inhibiting dust on the second area from marring the coating, and protecting the second area from coating overspray. Also disclosed is a masking system including the barrier strip of masking paper pressed against the film of the masking composition applied to the painted portion of an automobile. The masking composition is easily removable by a water wash after coating of the unmasked area of the automobile.

Abstract: A masking solution to settle dust and safeguard against overspraying in the area of a vehicle not to be painted, predominately an aqueous solution containing a carrier (e.g. glycerol), a surfactant and Xanthan gum.
