3 Ounce Water Finding Paste

Works great

If you have a moisture problem with your fuel this is the best detector of water and simple to use.

Nice product and very decent price

I purchased this to test the fuel in my neighbor's boat. After pulling a sample from his fuel line and one from the tank, we left them to sit in mason jars to see if there had been any separation. Although none was seen, we put a smear of the paste on two index cards and dipped them into the jars. No indication. We tested a control sample with some water mixed in with the fuel, and the color instantly jumped to red. I'm not sure if its able to indicate how much water is in the fuel (different shades), but it definitely did tell me that the control was contaminated. This is great stuff and saved us time in diagnosing an issue, as well as the time and cost of potentially having to polish all of that fuel.

Works as advertised. Used to detect water present in heating oil tanks. Nice to know to detect a leak before winter and you do not have heat when it gets below freezing. Test tanks at houses couple times a year.

works just like it should

Great quality. Cut the downspout and install. I would recommend cutting the downspout at the same angle as the assembled diverter so it will have a more professional appearance.

Good for testing gasoline for waterbefore pouring into a lawnmower.A repairman will charge a price tojust drain your gas tank. Avoid thatby testing your gas.
