Back in the old days spraycans were really toxical, but that doesn't mean they are now "healthy". With this page I also want to open the user's eyes to take care of his health. IT is not only about the lungs but also about the skin, eyes, throat...
Always wear gloves and I deeply recommend to cover as much as possible from your body when painting. Spraycans can influence your skin, it makes it dryer. In order to protect it I advice to cover your skin with a protective coat of (almond) oil. Afterwards it will be easier to remove the paints and your skin will stay much longer young :)! If you paint every day/lots of hours a gas mask is highly recommended. Avoid eating in the painting area. Eating apples after painting are said to be like a "filter". If possible also wear glasses to protect your eyes.
Currently I do not have any more gas masks in stock but the ones I sell are the most comfortable with the best price/quality.
Take a way, stay safe!
