Yeah but, my neighbour did his with a spray gun whilst we were away on holiday. Sprayed the side of our house and the white UPVC windows and the back door. Only realised when his wife pointed it out and spent the next two or three days cleaning it up!
The neighbour behind my daughter did his and the spray carried the mist the length of the garden and through the kitchen window and stained some cupboards and the work surface!
