  • High quality product and very visible
Size: 32 oz
Great product and i am buying it again. I use a little less than the directions say because it is very blue. The product is think and will sink. I used a small drywall mixer attached to a drill to mix it in evenly. Spill this on yourself and you are transformed into a smurf for 24-48 hours. Wear gloves. ... show more

  • Value!
Size: 32 oz
Super dark and concentrated! Doesn't take a lot. The original cap had a crack. The dye drips everywhere even if you're extra careful. Wish I had a special spout for better pouring. You get more for the money.

  • This stuff will dye everything and it's awesome!

  • Works great
Size: 32 oz
This stuff works great. Beware not to spill it or drip it on anything you don't want turned blue though. it will stain very easily. Only takes a little bit in the sprayer and mixes very well. Highly recommend.

  • Does What It's Supposed To Do
Size: 32 oz
This stuff works, it marked where I sprayed so I didn't apply in the same place twice. I recommend following the directions closely it only takes a little bit of this stuff to mark your yard. It will absolutely stain anything it comes in contact with so be careful around driveways sidewalks edging etc. I wore gloves and I'm glad that I did and figure that your shoes will be blue too. Interestingly enough it did not stain the inside of my backpack sprayer, I figured that I was going to have a blue tinted sprayer from now on. I like that it also has the wetting agent already added to it too. It does take a long time for this to dry on the grass though. For me it was about five days and my wife was not happy about having to walk our 2 dogs down to the vacant lot for them to do their business. ... show more

  • Really helped worked great for me
Size: 1 Gallon
No doubt a bit messy so you gotta lay down something like cardboard or something to keep from getting everything blue. Make sure you wear gloves and clothes you don’t care about if you’re careful it’s not that bad but this stuff really works. You can see where you’re spraying and it lasts a long time. It does get on the concrete, but it’s not a permanent stain. It will run away eventually you can pressure wash it easily. ... show more

Don't get it on you. Hard to get off. Works good for indicating what you have sprayed though.

  • Just not worth it
Size: 32 oz
Oh yeah it marks where you sprayed weed killer, and also dyes everything else it touches. Just not worth it, use regular non-dyeing surfactant.
