Look for in a Quality Automotive Sealant

Sealants come in many formulas, making choosing the right one for your repair project challenging. However, knowing what features to look for can help you select a high-quality product that fits the bill.

Keep these five things in mind the next time you are in the market for a car sealant to make the task easier.

1. Your Preferred Application Method

There are various ways that car sealant can be applied. When using sealant on a vehicle, you need to match the application method to the location and material. For example, you wouldn’t want to use a precision tube application for large areas like floorboards or a trunk. Several popular application methods include spraying, brushing, or using a cartridge gun.

Remember that you will also need the proper tools for your chosen application method. That might include brushes, cartridge guns, or sprayers, depending on the formula you select. Keeping these things in mind will help you choose a product that works for your specific repair project.  

2. The Desired Temperature Range

This is a concern that must be taken seriously during auto repairs. Automotive sealants in some parts of a vehicle, particularly those around firewalls and near the engine or exhaust, must be able to withstand extreme temperatures.

If you are purchasing a sealant for these applications, be sure it is designed to work in those temperatures. 

3. The Materials You Are Using On

Another thing to consider is the material you are applying the car sealant to. Some products can only be applied to bare metal. Others are suitable for primed and painted surfaces.

You will also find several types of sealant that can be applied to non-metallic surfaces. These are excellent for windshields and areas where you need to seal plastic or fiberglass components.

As a general rule, you want to be sure the following specifics of a sealant match the needs of your project:

  • Bond strength
  • Suitability for painted, primed, or bare metal
  • Adhesion to non-metal surfaces
  • Orientation of surface
  • Resistance to contact substances 
  • Low or zero VOCs for poorly ventilated areas

4. Paintability of the Finished Product

Like with other types of adhesives and sealants, some car sealants are paintable, and some are not. Additionally, some will accept a textured finish while others are smooth.

Therefore, you’ll need to shop for a product with the desired qualities to finish the component getting appropriately repaired. Luckily, plenty of products work well and can be painted to your desired finish color. 

5. Resistance to Chemicals and Oils

Any time you work on a part exposed to caustic chemicals or oils, you want to use products designed for direct contact with these substances. Otherwise, the chemicals could wear through your car sealant, causing leaks, gaps, or loose parts.
