Regularly cleaning under a car is essential, especially after the

The process usually involves a high pressure spray being poked
the wheel arches and various other nooks and cranies, along with
of groveling around to try and see if there are any stubborn bits
on, in the face of the watery onslought.
These clingers are difficult to see, because the underseal is always
i.e. the same colour as the reluctant detritus, but this problem is
solved with the introduction of The Chassis Graph.
If you choose to have The Chassis Graph treatment applied to the
underside of your car, before it's delivered, its weather-proof

it. These lines run at right angles to each other in both directions
the pattern of a graph the covers the entire underbody of the car.
With your Chassis Graph in place, cleaning now becomes a simple
of spraying away until the lines clearly reveal themselves against
