A corrosion resistant flashing product may comprise a polymeric composition that is substantially weatherable such that the flashing substantially retains its original properties after prolonged exposure to the outdoor elements while also providing substantial resistance to ACQ or CBA corrosives. In a preferred embodiment, the polymeric material comprises one or more light stabilizers from about 0.3% to about 15% by weight; one or more acrylic impact modifiers and/or process aids from about 2.5% to about 10% by weight; one or more thermal stabilizers from about 0.25% to about 3% by weight; one or more waxes or lubricants (or systems) from about 0.3% to about 7% by weight, and one or more plasticizers from about 0.1% to about 10% by weight.
