A new product has been created called ultra-ever dry. You have to see it to believe it! Although it is highly toxic, and rather expensive, the uses and applications of this product seem endless. Fully waterproof clothing and clothing that never gets stains of any kind. Never having to wash your windows again. Even graffiti wouldn't stick to buildings treated with this product.
Watch the video and be amazed.
