Follow This 8 Steps to Waterproof Your Truck Cap
Step 1. Prepare the Truck Cap:
Clean the cap thoroughly with a cloth and warm, soapy water. Then use sandpaper to remove any paint from the edges of the cap. Flip the truck cap over and use a damp cloth to remove any dust or dirt.
Step 2. Apply Sealant:
Using a paintbrush or foam brush, apply a generous amount of silicone caulk or liquid rubber compound to all edges and seams of the truck cap.
Sealing the cap to your truck bed will help protect your truck from water damage. Ensure you’re applying the sealant continuously and filling any gaps or holes.
Step 3. Add a Few Layers on the Bulkhead:
You can apply a few extra layers of silicone caulk or liquid rubber compound on the bulkhead for additional protection.
This will help to ensure that no water leaks into your truck bed. You should also ensure that you’re creating a continuous line of sealant around the entire bulkhead.
Step 4. Wait for the Sealant to Dry:
Once you’ve applied the sealant and added extra layers to the bulkhead, it’s time to let everything dry.
Wait at least 24 hours before you move on to the next step. You may damage your truck cap if you try to do anything before the sealant has fully dried.
Step 5. Check the Taillights:
Before moving on to the next step, ensure your taillights are properly sealed against water damage.
To do this, use a cloth and warm, soapy water to clean around the edges of the taillights. Then apply masking tape over each light and spray it with silicone caulk or liquid rubber compound.
Step 6. Check the Weather Stripping:
Weatherstripping should already be in place to help protect your truck from water damage, but you should still check it now and then to ensure it’s functioning properly. If you notice gaps or holes, apply a generous amount of silicone caulk or liquid rubber compound.
Step 7. Apply a Second Layer of Sealant:
After the first sealant layer has dried, it’s time to apply a second layer. To ensure that no water leaks into your truck bed, create a continuous line of sealant around the edges and seams. If there is any excess sealant, remove it with a clean, dry cloth.
Step 8. Double Check Your Work:
Once you’ve finished applying silicone caulk or liquid rubber compound, it’s time to double-check your work.
Make sure that all edges and seams are properly sealed and that any extra layers of sealant have been applied correctly. If you spot any areas that need to be fixed, go back and apply more sealant.
Your truck cap is now fully waterproofed! You can protect your truck bed from water damage and keep your cargo safe with a few simple steps. Enjoy the peace of mind that comes with knowing your truck is protected!

If you’ve noticed that your truck cap is leaking, it may be time to take some steps to fix the issue. First, check the weatherstripping and ensure it’s in good condition and not cracked or damaged.
Then inspect the sealant around the truck cap’s edges and ensure all gaps and holes are filled. If you find any areas needing fixing, use a clean, dry cloth to remove any excess sealant and then apply a generous amount of silicone caulk or liquid rubber compound to the affected area.
Finally, test your truck cap by spraying it with water and checking for leaks. If everything looks good, your truck cap is now protected from water damage! Enjoy your waterproofed truck and the peace of mind of knowing it’s safe.
