Used this on the underside of a 50" garden tractor mower deck. Fantastic stuff! Grass basically completely stopped sticking to the underside. Mower also performs better in thick wet grass now. Proper preparation is key. I scrubbed off all rust with a wire brush, then pressure washed, then sanded, and then rinsed with degreaser multiple times. Make sure you go above and beyond with the prep work, and you'll be happy you did.

I dont know how anyone can say this keeps grass from sticking to their deck. I stripped the whole deck, repainted the outside and used this on the inside. Let me tell you, grass sticks worse than ever!!! I actually have to get down on the ground, scrape out inch plus thick grass with a putty knife and spray wd-40 on as much of the deck as I can reach every time I mow or it fills the deck, throwing my blades off so the grass cuts uneven. It's awful. I busted my butt cleaning that deck up and regret using this stuff...made it a complete waste of time. Stay away!!
