Spray paint is a versatile medium that can be used on a variety of surfaces. However, it is also susceptible to chipping and fading if not properly protected. There are a few different methods of hardening spray paint, each with its own benefits and drawbacks.

The most common method of hardening spray paint is to add a clear topcoat. This will protect the paint from UV rays and other environmental factors that can cause it to fade. However, it will not protect against chipping or scratches.

Another common method is to mix the paint with a hardening agent. This will make the paint more durable and less likely to chip or fade. However, it can also make the paint more difficult to work with and may change the color slightly.

Finally, you can also buy hardening spray paint that is already mixed with a hardening agent. This is the easiest option, but it may be more expensive than buying the separate products.

Which method you choose will depend on your needs and preferences. All three methods will protect your spray paint from fading, but only the hardening agent will also protect against chipping.
