Will Spray Paint Explode in a Hot Car

No one knows for sure what will happen when paint and other volatile aerosols are left in a hot car, but it’s something to be aware of if you want to avoid a potentially dangerous situation.

What is Spray Paint?

Spray paint is made up of a variety of solvents, and when the paint is put in contact with a hot object, the solvents can cause an explosion. The most common type of spray paint is automotive paint, which is specifically designed to resist heat. However, any type of spray paint can explode if it’s put in contact with a hot object.

How does Spray Paint Work?

Spray paint is a type of paint that is applied to surfaces using a hose, can, or other applicator. The paint is ejected from the applicator in a fine mist and then “sprays” when it hits the surface.

The paint works because of the heat of the sun and air. When the paint hits the surface it melts and drips down. The heat from the sun and air makes the liquid form gas bubbles which expand when they hit water or other liquids. This causes a sudden increase in pressure which can cause the spray paint can or hose to explode.

Can Spray Paint Explode in a Hot Car?

There is a lot of speculation on the internet about whether or not spray paint will explode in a hot car. The answer to this question is actually pretty simple – no, it won’t.

The main reason why this doesn’t happen is because the heat from the sun and the heat from the car itself will cook off any raw materials that may be present in the paint. In fact, you would need temperatures well above 1,000 degrees Fahrenheit to create a real explosion.
