Spray paint is a type of paint that comes from aerosol cans. It really stinks for anyone who can't maintain a steady hand for any more than two hours. Drying time is poor and the price is high.
Graffiti artists use this product to quickly make ugly graffiti tags.... and of course 80's clothes designers.
Spray paint often uses toluene as a solvent. As inhaling toluene can be dangerous, contents of cans should not be deliberately concentrated or inhaled. Use in a well-ventilated area, like a bridge or a radio antenna.
