What partly inspired the project was the idea to emulate the racing numbers and sometimes makers names, stencilled onto the radiator grills of vintage racers particularly those lovely early Alfas. It probably worked better on the large car grills as the mesh makes for rather large "pixels" as it were, but I'm still pleased with my efforts and it looks much nicer than the tatty cooler matrix.
You could probably spray the whole thing black and make it disappear while still protecting the cooler and tidying it up at the same time.. Looking forward to seeing how folk decorate them.
