I kave used POR-15 frequently as a body man. Be EXTREMELY cautious when spraying. POR-15 is as isocyanate, similar to superglue. Without a proper resirator you are effectively sucking in superglue! Disposable mask are not good for spraying. I always use a brush or roller because of this. Use the following link to learn more on the safety facts.
