   Good stuff. As described marks weed killer area where sprayed so there’s no spraying the same spot twice. WEAR DISPOSABLE GLOVES! As others have stated, the concentrated liquid color is thick and stains easily. Once diluted and applied it fades away which is a plus.Only negative is the bottle with the measuring side. Can’t see the amount because the dye sticks to the sides so cannot see how much is in it. So I just use a small disposable measuring cup.

   Très pratique pour savoir ou l’on utilise les produits de traitements.La couleur disparait en trois jours sauf sur les murs. ATTENTIONIl faudra utiliser un nettoyeur haute pression pour faire disparaitre les taches.Utiliser des gants car sur les doigts ça reste malgré un nettoyage intensif.

   I was shocked at how much easier this made the job of spot treating for weeds. Since I could mark the weeds I’d treated, it enabled to focus much more clearly on places that I knew for sure I had not already been. Doesn’t seem like that would make a big difference, but for me…it did.I did use the product at a pretty strong mix. 1 ounce for a gallon, versus the suggested 1/2 ounce. Thus, your spots may not be quite this blue!

   I’ve usually just guessed how much liquid chemical I’ve applied before but this helped me make sure I got the right coverage.I barely used any in a 15l tank and could see exactly where I’d applied weedkiller. It made the job much easier.I did get some on my shoes but it wore off fairly easily with general wear,
