Sta-Kool 805 Metal-X is a tough, white elastomeric roof coating that is formulated for exceptional bonding strength to metal roof surfaces. This high performance product also contains rust inhibitors, which provide long-term protection to metal surfaces. Metal-X expands and contracts with the roof’s movement to resist cracking and peeling. The bright white finish keep metal roofs cooler by an average of 50 degrees compared to uncoated metal, thus minimizing heat stress associated when metal roofs expend under the hot sun. Metal-X provides a protective barrier that reflects, seals, and protects from the element. In turn, this provides a longer life to metal surfaced, helps to cool surfaces and will help reduce interior temperatures. This environmentally advanced formula helps reduce energy cooling demand, is low odor, and low VOC, making it a great choice for your metal roof. Covers approx 50-75 sq. ft. per Gal.

Rated 4.8 out of 5 by 4 reviewers.
Rated 5 out of 5 by good product and easy to use good product and worked as advertised. Easy to apply and resulted in good coverage. Definitely needed 2 coats as recommended. Only negative is that it is only available in 5 gallon cans. June 3, 2014
Rated 4 out of 5 by It works! We painted a leaking metal roof on an old mobile home. We pressured wash the roof first. We applied the sealing compound where necessary then painted the whole roof. It rained a week or so later and the leak was gone. April 2, 2014
Rated 5 out of 5 by Performs well so far... This coating was pretty easy to apply on an old metal roof and has held up well during the first few months of fall and winter. It seems to be a good idea to pay close attention to the manufacturer's recommendations as to appropriate weather conditions and application methods. I applied it to a decades-old tin roof (about 200 square feet, over a garage), which had previously been covered with a black asphalt-based coating. The white elastomeric coating has provided full coverage, but it required two applications (just as the manufacturer had recommended). Because of fall weather conditions, the coating was applied at slightly cooler temperatures than recommended; and unfortunately there was an unpredicted rain shower less than 48 hours after the first application. The result was that the coating took slightly longer to dry, particularly in spots and along seams where the coating had been thickly applied; and several very small sections were washed out by the unexpected rain. Nevertheless, the second coating took care of all of the problems. Patches that were initially applied with water-based products have held up well too, after the coating was put down. The bright white color looks a lot better than the old black, asphalt-based coating. Because it's water-based, clean-up was pretty easy. It should do a good job of reflecting sunlight from the old roof. So far, it's been holding up well and providing a good seal. Of course, time will tell. January 19, 2014
