This hazardous (no mention) in the sales pitch. The medium does as stated, drys to a perfect matt finish for that 2 stars would be 5 if it wasn't so hazardous, the fumes are intense and can cause severe health issues, ventilation like working outside in open air would alleviate the symptoms, indoors, forget it. The medium skins over in the can and eventually any remaining medium sets rock hard. I lost 2/3 of the content despite adding glass marbles to take up the volume. So I would say buy a gas mask or avoid it. (Posted on 09/06/2023)
