Abstract
Methods and compositions are provided for protecting exterior surfaces of automobiles and other products, or components of products, against abrasion, abrasive dust, water, acid rain, etc. The methods involve applying to a surface a protective coating composition comprising a polyvinyl butyrate emulsion and a relatively inert extender. The emulsion is dried to form a water-resistant protective coating that can be removed from the underlying surface by peeling when no longer desired.
