How Do I Seal My Truck Camper Shell?

Sealing your truck camper shell is a great way to protect it from the elements and ensure its longevity. There are a few different ways to do this, depending on the type of shell you have and the materials used. One of the most popular methods is to use a plastic sealant. This type of sealant is applied directly to the outside of the camper shell, forming a watertight barrier that helps keep out moisture and dust. It’s also relatively inexpensive and easy to apply, so it’s an ideal choice for those looking for a quick fix.

Another option is to use a rubberized sealant. This type of sealant uses rubberized compounds that form a more durable, long-lasting bond than plastic sealants. It is often used on metal shells, as it is more resistant to corrosion and wear than plastic sealants.

Rubberized sealants also tend to be more expensive than plastic ones, so it’s important to consider your budget when choosing this option.

Finally, you can also use fiberglass tape or butyl tape. Fiberglass tape is similar to plastic or rubberized sealants in that it forms a watertight bond with the camper shell. However, it’s often used in conjunction with other materials like silicone caulk or butyl tape for added protection against moisture and dust. Butyl tape is similar in that it creates an air-tight seal between two surfaces, making it another great choice for sealing your camper shell.


Sealing your truck camper shell is an important step when it comes to protecting your investment from the elements and ensuring its longevity. Depending on the type of shell you have and the materials used, there are several different options available including plastic sealants, rubberized sealants, fiberglass tape and butyl tape. Be sure to consider your budget when selecting an option as some products can be more expensive than others.

No matter which product you choose, sealing your truck camper shell will help keep out moisture and dust while extending its life.
