How Do You Seal a Truck Bed Topper?

A truck bed topper is a great way to increase the storage capacity of your truck bed and keep items safe from the elements while driving. However, if you want to get the most out of your topper, you need to make sure it’s properly sealed. This will help keep out dirt, dust, and moisture that could damage cargo and compromise the security of whatever you’re carrying.

The first step in sealing a truck bed topper is to inspect it for any existing damage. Look for cracks or gaps that could allow water or dust inside.

If you find any, fill them in with silicone sealant or a rubber-based sealant made specifically for use on truck bed caps. Make sure to wear protective gloves when applying these sealants as they can be hazardous if inhaled.

Once the sealant has dried, cover the entire surface with a layer of adhesive-backed foam weatherstripping. This will create an airtight barrier between your cargo and the elements outside your vehicle. Be sure to press down firmly on the weatherstripping so that it adheres completely.

Finally, apply a coat of automotive grade wax over the entire surface of your truck bed cap. This will help protect it from corrosion, scratches and other damage that can occur from exposure to wind and sun.

Conclusion:

Sealing a truck bed topper properly is essential for keeping out dirt, dust and moisture and protecting whatever cargo you may be carrying. Start by inspecting for existing damage and filling any gaps with silicone or rubber sealant before applying adhesive-backed foam weatherstripping across the entire surface. Finish by applying a coat of automotive grade wax over everything for additional protection against corrosion and other wear-and-tear caused by exposure to wind and sun.
