What to Consider When Choosing a Car Undercoating Spray

While car undercoating sprays might seem as though they’re all the same, there are some differences between them. In order to choose the undercoating spray that is right for you, you must take these differences into consideration.

When attempting to make a purchase, pay attention to differences in volume of spray, functionality, durability, and any special features that sprays may possess.

Volume

Car undercoating sprays come in containers of all different sizes. Whereas some come in small bottles of 12 ounces, others come in large jugs of 1 gallon.

Neither size is better than the other. It’s just important to consider how much you’ll need in the near future, and to buy accordingly.

Functionality

When it comes to overall functionality, all undercoating sprays are a little different.

At the bare minimum, they should be able to provide some reinforcement to the undercarriage of your automobile.

Added functionality includes everything from sound deadening, to aesthetic enhancement, and more.

Durability

Whereas some undercoating sprays can make it through about a year without wearing off, others can only make it a few months.

Keep an eye out for an undercoating spray’s durability capabilities. It’s better to spend more money initially than to have to constantly apply your spray.

Special Features

For the most part, car undercoating sprays are fairly basic. They do the job of reinforcing your car’s undercarriage, and not much more. However, some are adept at lessening the amount of noise that makes its way into your car. By essentially closing up the bottom of your car, they can do a lot to eliminate road noise.
