Gasoila Gas Gauging Paste, Detects Water In Fuel, Gasoline, Diesel, Kerosene, Petroleum, 2.5 oz. Jar

Works well enough.

Great product

It does work but its very messy.

Great product! Awesome quality!

It doesn’t work as well with diesel fuel. Got it to sound the tanks on our fireboat.

says a paste but mine was like chocolate syrup

Great stuff!

Use this to test for jet fuel in oil water separators at our fuel farm. Works good.

great

It works...you can see the fuel level clearly...you just have to wipe and reapply often. Beats using chalk.
