Tetrosyl Touch-In Paint Pen
Price: £3.69
A novel twist on touch-up paint which puts the colouring in a marker-style pen. On stone chips, the idea works really well because, with patience, it’s possible to build up the layers without getting surplus colour on the surrounding bodywork. Obviously, the approach doesn’t work as well for deep scratches, and we felt the pen nib should have been slimmer.
