added to my weed killer to mark what i haven't sprayed yet to save on over spray

Good for the price and it stayed green for longer than expected. It was easy to apply and even though in the pic it might look too bright of a green, it wasn’t like that in person.

Real good product when mixed right

Since I was applying new grass seed in certain areas of been sprained and killing weeds and other areas, it was nice to clearly see where my weed killer was, and I was able to lay new seed down areas from the painted weed killer

Work great do the job well

I use this in my tow behind field sprayer. I don't know how I would be able to do that job without this stuff, It shows me right where I've applied fertilizer and where I missed. It also helps me know how much of an application I'm putting down. One of my favorite things is that it fades quickly and since it's green it blends anyway. I do recommend working in one area at a time because of how quickly it can fade, it's most visible while it's wet.

Too messy. It dyed the grass green but it lasted only a few days. When it rained the dye went down to the sidewalk. After 4-5 rains ; the sidewalk stains disappeared.

The green was really tough to see on the grass, kind of defeated the purpose I was using it for.

Pretty good stuff, I mixed it a little stronger than recommended, I was using it for dye marking so I knew where I'd sprayed the more expensive product I'm using (and it doubled as a way of seeing how contaminated I got) and well... it works. It was a little harder to see the difference when I was spraying at dusk after work but it's very obvious in the sunlight. Left side of the photo is treated grass, right side is not (I'm not spending on the council property lol)
