DON'T PAINT YOUR CONTAINER before watching this

I tested Henry 817 Roof Guard on a steel shipping container in 85º Arizona desert. UV protection, waterproof, reflective — but does it actually hold up? I put this "urethane-enhanced" white coating to work to see if it really drops interior temps and stops ponding water. This is not sponsored — I bought the bucket myself at Home Depot. WHAT IT CLAIMS (from Henry): • Premium acrylic-polyurethane hybrid for better weather protection, solar reflectivity, and longevity vs standard acrylics • 100% waterproof, permanent ponding water resistant • Dirt Pick-Up Resistance (DPR) technology for longest lasting reflectivity • Lowers roof and interior temperatures, 25-year limited warranty with one application • Coverage approx 100 sq ft per gallon per coat IN THIS VIDEO: 0:00 Intro 1:25 Setting up camp 2:22 Dealing with slide issues 7:18 Prep: washing container 11:08 Rest & talk 13:03 Painting day 21:27 The results 24:01 outro MY SETUP: • Surface: 40ft steel shipping container, marine painted metal with heavy rust spots • Product: Henry 817 Roof Guard, 4.75 gal white • Tools: 3/4" nap roller, wire wheel on angle grinder, mop & water • Location: White Mountains, Navaho county — applied early June. RESULTS: • Day 1 temp drop: 40°F on interior/exterior roof 10º cooler inside container, after paint, on the hottest day. 3º warmer • Any peeling/blistering: None so far WHERE I GOT IT: I couldn't find a Home Depot that carries it in stock. They do carry the tropicool silicone version, however Roof Guard 817 in 0.9 gal and 4.75 gal must be ordered. Check stock locally (Not an affiliate link) COST BREAKDOWN: 5 gallon Bucket: $205 each | about 320 Total sq ft covered: FAQ: Q: Can you use 817 on RVs, metal, or mobile homes? A: Henry lists metal, concrete, EPDM, TPO, PVC and more. Always check the data sheet for your roof type. however, I personally would not apply 817 acrylic Roof Guard on a RV roof that travels. Q: Do you need primer? A: On weathered & bare metal I'd use primer — follow the TDS. DISCLAIMER: I'm not a roofer. This is a DIY field test in extreme desert conditions. Always follow manufacturer instructions and safety data sheets. Your results will vary by prep, climate, and application thickness.
