The spray disappears when washed, and does not affect the colour or surface of the textile. The spray lasts for approximately a week after application, depending on the texture of the surface you spray, how much you apply and how often the garment is worn. In cases of heavy wearing you should add more spray continuously for full effect, or regularly check the reflective effect.

The reflective effect can easily be controlled by shining a light at eye-level upon the sprayed surface or taking a photo with flash. E.g with your mobile phone camera.

You can easily create reflective signs and symbols by cutting out, and spraying on with stencils.
