It's like a baking soda type powder. Just heavier. It will remove the paint without damaging the finish of the metal/fiberglass. You'd have to cover and be careful with your windows cause the air pressure from the blast can blow them out, but fast and effective. You can even wash away the blast material with a water hose.wannawangan wrote:I've heard about soda blasting. What is this soda stuff? Sodium bicarbonate? Coke or Pepsi?
