Zinsser Peel Stop triple-thickness binding primer locks down peeling paint and seals weathered surfaces on a range of interior and exterior surfaces, including wood and aluminum siding, trim, metal gutters, and fiberglass. Its low-odor and low-VOC water-based formula means it can be used on or beneath any oil- or water-based topcoat, and it expands and contracts with changing temperatures. Peel Stop is available in in quart, gallon and five-gallon sizes. 877.385.8155. www.zinsser.com
