When it comes to what you should drink after spray painting, there are a few different options that you can choose from. Water is always a good choice, as it will help to flush the chemicals out of your system. You can also opt for milk or juice, as these will help to neutralize the chemicals in your body. If you are feeling particularly thirsty, you can even drink a sports drink like Gatorade, as this will replenish your electrolytes and help you to stay hydrated.
