I was thoroughly impressed with this product. I have a WWII era Quonset hut that is partially covered by a roof and partly exposed. The exposed part was getting rough but not rusted through anywhere. I cleaned with a very stiff bristled brush and rinsed with hose and let dry. This stuff covered amazingly. I couldn’t believe how much coverage I got out of this. I ordered 10 gallons and was afraid that might not be enough. I ended up only using about 4 gallons. I even tried to apply it as thick as I could. It fills in and covers pin holes and old screw holes very well. For reference I painted the end 10’ of Quonset hut with 4 gallons. This also works good for dipping tool handles into such as pliers, channel locks, or hammers to put a new rubber coating on them. I wasn’t sure about this product when ordering but I am completely satisfied and can definitely recommend. Worked great for me. It did stop all of my leaks btw.

Covers metal really well and is very sticky. Wear old clothes when applying and don’t let your cat walk by it.

It’s hard to tell, I used it as an under coating for my truck bed that I cut out and replaced! It painted on real thick. If it stays playable and holds on, it will be good!! It’s got to be better than just paint!!!

used this to seal up my metal roof that had some leaks, very easy to apply. The material is strong and coverage is great, this was a cost effective solution to provide extra durability to my structure.
