Stains on the floor under the vehicle are usually not a good sign. The challenge in repair is always to find the leak. It is usually so small and also well hidden in the dirt of the engine or gearbox that it is difficult to find. With the new presto Wet Leak Finder, finding the fault is now made much easier.  After a short test drive, the black engine oil or brown transmission oil will show up clearly on the white powder layer that forms. Other liquids also leave their traces on the powder layer. This way, you can quickly find the damaged area and repair the leak. The presto Wet Leak Finder is therefore universally applicable for locating leaks of oil, fuel or other liquids and is also easy to remove after use.
