Top Uses for Automotive Sealant

Automotive Sealant

Automotive sealants are vital to ensuring weathertight interiors. They are also effective at limiting corrosion, reducing drafts, dampening noise, and creating long-lasting bonds. When you consider all of these uses, it’s not surprising that a quality car sealant is one of the most versatile products in your shop.

Undercoat Coverage

A high-quality undercoat sealer can be used in a variety of applications. For example, it dampens cabin noise and keeps dust and water out of cabin interiors. It also helps limit corrosion on undercarriage components. Our rubberized undercoat sealer is often applied to areas including:

  • Fender wells
  • Trunk seams
  • Floor seams
  • Frames
  • Doors

Pipe Thread Seals

Metal threads can work loose in high-vibration environments. Pipe sealer with PTFE eliminates this problem. It creates a permanent seal on contact, so you never have to worry about parts working loose. At the same time, a low locking strength means you can remove the part if necessary.

If you need to use pipe sealant in an internal component, choose one that cures without air contact. This will ensure proper curing once applied. Also, shop for products that can withstand any grease or chemicals they might be exposed to during use to avoid deterioration.

Seam Repairs

Filling seams is one of the top uses and one of the best uses for car sealant. Most body rust starts at seams where exposure to moisture and dirt kick starts the process. This can ruin an original or newly restored finish. When applied, a sealant blocks these contaminants and helps prolong the car’s finish.

This is helpful in two main ways. First, prolonging the vehicle’s appearance ensures your hard work restoring a vehicle is not wasted. Car sealant can also help stop minor drafts and leaks in an older car that is starting to show its age. Blocking them can give you the time necessary to make repairs or begin the restoration process.

Be sure to choose the correct application method for sealing sacks and leaks. For example, a spray may offer excellent coverage over large areas, but you may need something more substantial to fill holes.

Creating a Smooth Finish

A high-quality car sealant makes it easier to achieve a smooth finished paint job when applied to body seams. Sealants remove variances between panels and ensure they are correctly connected. This provides a stable and smooth canvas for your final paint job. If you’re looking for more automotive tips and information, be sure to visit

Additionally, primers help create a bond between the paint and the car’s surface. This provides a smoother, more uniform finish that resists moisture infiltration. That is why taking the extra step of sealing a surface before the paint can help prolong the finish.
