Hi there! I am in the need of assistence regarding my project. I will probably have availible a small patch of asphalt (cca 1 square meter) and I would love to do some art there. I have picked the motive and planned it out in the photoshop, but it will require like 7 colors and so I would want to do it as cheaply as I can (under 20€$) and I would like the result to last as long as possible. I am considering spray or bucket of paint and some pigments, but I am open to all your suggestions and tips. The asphalt is in the open and so it will be subjected to rain and snow and people will walk on it probably, so I am looking for something pretty durable. Thanks.
