If you own a Tonneau cover, you may know that it is vital to make sure that it is waterproof.
After all, if you are driving a truck, there is a huge probability that you carry something in the back that you don't want to get wet. Right?
Sadly, not all bed covers are completely waterproof. Because of this, many people have taken the matter into their own hands, and they have added a few features to make them entirely (or almost entirely) waterproof.
Because of this, we bring a few tips that you could use to make your bed cover a bit more waterproof than it already is.
Keep reading, since you may be surprised by some of these tips!
How to Fix Any Leaks on My Tonneau Cover
Most Tonneau covers come with a seal or a rubber side to keep water from entering the bed, but in most cases, these seals are not enough.
Even with multiple seals, water will filter eventually, but there are a few solutions to this.
Water Pipe Insulation
This may prove to be one of the most popular solutions since it is so fast and economical to install on your truck. In most scenarios, water may be filtering through a gap or unsealed space.
Because of this, you may want to find a way to seal these gaps yourself.
Now, these water pipes are made from rubber, and you can find them in almost all hardware stores.
These are usually pre-slit, and they may also have some adhesive in the edges, so they are easier to install.
They are pretty cheap and easy to use. You just need to adjust them under the edges of wherever the water is filtering, and as soon as you cover the bed, you will see how these pipes create a secure and tight seal with the cover.
If the leakage is not that big, this can be a fast and straightforward solution. You will have to add a few more seals to space where the water is leaking.
You can discover these in any hardware store around, and they come in a variety of sizes. Bear in mind that a big seal may not be the best option in any scenario.
If the seal is too big, it may move the seals that are around it, which may lead to more leaks.
Bed Seal Kits
These kits are without a doubt the best option in most cases. They have everything you need to seal and waterproof your truck's bed completely.
From extra seals to foam blocks that will help you seal the underside of the bed rails, it has it all.
You may have to look a bit more to find these, but once you find it, you won't need anything else to fix any leakage.
They have an instruction manual included, which will guide you through all the process.
Some of these kits also include a drainage system. This is a great plus since they help dispose of water that may begin to gather on certain parts of the bed.
Nonetheless, the only drawback to them is that they are a bit more expensive.
But in the end, they are really worth those extra bucks if it means that it will keep the inside of the bed completely dry.
Tests You Can Do to Make Sure the Cover is Completely Sealed
Once you are finished fixing all the unsealed parts of your truck’s bed, you might want to test them.
Mostly because you don’t want to be caught off guard the next time you are driving through a storm or heavy rain.
Because of this, testing them just after you have finished may be a great way to make sure that what you did works.
To begin with, you could try looking for any parts where the sun filters through.
Park your truck outside during a sunny day and close the cover. If there is any space that is not covered, the light will penetrate through, and the inside of the trunk will not be as dark.
The problem is, you see it from outside with the tailgate unlocked, which means that your eye can deceive you.
But don't worry, since there is a way to be entirely sure, but if you are claustrophobic, you won't like it.
To be sure there is no light filtering, you may want to get a look at the inside when everything is closed. To do this, you could climb under the bed cover and have someone else close the tailgate.
If its dark to the point where you can’t even see your hand, we are good, and your cover is completely waterproof.
If not, you may have to continue working on patching those gaps.
Another way that you could try this is a bit simpler, but if you did fix the gaps, you might have a lot to clean.
You'd have to throw water on top of the cover and see if it keeps the inside clean.
Make sure that the water is disposed in the right way and that it does not gather somewhere on top of the cover. This may lead to stains or ruined seals, and you sure as heck don't want that.
These are just a few tips that may assist you to stop your Tonneau cover from leaking.
Bear in mind that there have been users that combine a few of these tips to make sure that nothing filters on the bed, even dust. So, go ahead and get creative!
