Fluorescent Dye

Fluorescent dye will turn ultraviolet light into visible white light, meaning it looks brighter and is thus highly visible.

We add non-permanent fluorescent dye to water, which we can then use for testing for leaks. The water is then poured on the outside of the vehicle where the leak is suspected.

This water is bright orange or green and can often be seen with the naked eye, but if not, the slightest trace will glow under ultraviolet light, enabling us to follow the trace from where the water leaks in, to where it ends up.

This is particularly useful when a car is suspected of having more than one leak, or water is pooling in several different places within the car, and is a vital tool in rain water leak diagnostics.
