For use on metal and fiberglass RV roofing (NOT RECOMMENDED FOR EPDM RUBBER OR TPO ROOFING). Dicor Elastomeric RV Roof Coating protects and beautifies metal, aluminum, steel, fiberglass and previously coated RV Roofs. Formulates with 100% acrylic elastomeric resins to form a rubber-like coating that will expand and contract with the roof movement. Brilliant white color provides superior reflectivity, thereby lowering interior temperatures. Requires two coats for adequate protection at an application rate of one gallon per 80 sq. ft. per coat.
