Frequently Asked Questions
Fiberglass tonneau covers are moderately weighted, typically ranging from 50-75 pounds depending on the design and features. While heavier than soft vinyl covers, they're generally lighter than solid aluminum alternatives. The weight represents a good balance between durability and manageability. Most models are designed to be handled by one or two people during installation, and their weight contributes to their stability once mounted to your truck.
Fiberglass tonneau covers offer moderate scratch resistance but aren't scratch-proof. They're more durable than vinyl covers but can still be scratched by sharp objects, tree branches, or improper cleaning techniques. The gelcoat finish provides some protection, but deep scratches can penetrate this layer. When scratches occur, they're typically more visible on smooth, glossy finishes than on textured surfaces. Minor scratches can often be buffed out using automotive fiberglass polish, while deeper damages may require professional repair to prevent moisture infiltration and structural damage.
Walking on a fiberglass tonneau cover is strongly discouraged for several reasons. Most fiberglass covers are not designed to support concentrated weight like a person standing on them. The pressure can cause the fiberglass to flex, potentially creating cracks or structural damage that may not be immediately visible. Additionally, fiberglass surfaces can become slippery, especially when wet, creating a serious fall hazard. Some premium, reinforced fiberglass covers may support limited weight, but manufacturers typically specify weight limits and whether the cover is designed for top-loading.
With proper care and maintenance, a quality fiberglass tonneau cover can last 7-10 years or more. Factors affecting longevity include exposure to extreme weather conditions, frequency of use, maintenance practices, and quality of the original manufacturing. Regular cleaning, UV protection application, and prompt repair of minor damage can significantly extend the lifespan of your cover. Premium brands with better quality control and materials often justify their higher price through longer service life and better warranty coverage.
Quality fiberglass tonneau covers offer excellent water resistance but may not be 100% waterproof in all conditions. The fiberglass material itself is waterproof, but the overall water protection depends on the sealing system around the edges and the design of drainage channels. Most premium covers feature rubber gaskets and sophisticated water management systems that direct water away from the truck bed. Regular inspection and maintenance of the seals are essential for maintaining water resistance. For absolute protection of sensitive items, consider additional waterproof containers within your truck bed, especially during extreme weather conditions.
