Gloucestershire based piker Rob Shallcroft says: "With Health and Safety at work ever increasing, there are firms who will make plastic drip trays to any size for industrial enviroments to collect oil and chemical drips and spills.
"Measure up the back of your car/van/bling mobile and get one made, they are tougher and much cheaper than the flimsy moulded ones made by the car companies. Handy for the Piker with the odd wet wintery thing in the back of the car."
