Abstract: An improved composition for protecting a vehicle, building, or airplane surface that will be painted or mechanically processed. For example, certain regions of a vehicle, building, or airplane may be masked in accordance with the present disclosure to protect those regions from paint overspray. The composition produces a film which adheres well to a surface to be protected, with few or no pinholes. Additionally, the composition can absorb any oil or grease present on the surface which can eliminate the need for towels and chemical solvents that may create toxic fumes, hazardous waste, and flammable hazards. Further, the material can be removed easily from the surface after use by peeling the film layer away from the surface.
