Video Transcript for WeatherTech TechLiner Custom Truck Bed Mat Installation - 2013 GMC Sierra

All right, today in this 2013 GMC Sierra we're going to install part number WT3TG03 from Weather tech. This is the Weather Tech tech liner custom tailgate liner. It's also a good idea to leave the liner out in the sun just a little bit to make sure it's completely flat after you take it out of the box. To start off our install, you want to make sure that the tailgate is completely clean. Next, we're going to have to attach three plastic strips to top edge of a cap on the tailgate. We'll go ahead and clean it off first with some rubbing alcohol to make sure we get rid of any wax or soap that's left over. We'll put them in place for now to make sure we have an even left to right.

Once they're sitting the way we want we'll go ahead and get a measurement to get an idea of where they're going to sit. Then we'll go ahead and remove them and then remove the backing from the adhesive, and then install them into place. We'll set them all next to each other and work our way across. Now there's a bolt and a center area we have to remove from the tailgate. We'll go ahead and remove that. We'll set it aside for now.

Now we'll go ahead and take our liner and lay it into place. Now, we're going to overlap the plastic strips a little bit so we know we have excess to fit inside. We'll go ahead and reinstall the bolt and snug it down. Then we'll take the liner and then flip it over to the side. On each side there are adhesive's that we have to remove the backing from there. This is for a hook and loop fasteners.

We'll go ahead and pull back the backing on all three places on one side, then lie it back into place. We'll lay the liner back down, make sure it's stretched out evenly and no wrinkles. We're done with the passenger side of the tailgate, let's go ahead and do the same thing on the driver's side. Once all of the adhesive have made contact with the tailgate we'll go ahead and take that top edge and tuck it into those plastic strips from earlier. We'll just work it in and makes sure it snaps in all away across and if needed we can go ahead and tighten down the bolt in the center as well. That's what it takes to install our custom tailgate liner, part number WT3TG03 from Weather Tech on our 2013 GMC Sierra. .

Stays in place,makes loading heave things much better because it protects the tail gate.Easy to clean up.

I was not impressed with the tailgate liner......specifically with the way it is to fasten to the gate using adhesive strips. This will not last long in the Arizona sun!



by:
2011 Chevrolet Silverado

Great product easy to install just follow the video! Quick shipping would order again.



by:

Fast shipping as advertised great customer service



by:

The TechLiner is a great product. It fit perfectly and looks awesome. You do need to let it sit in the sun for a couple hours to flatten out. This liner does velcro to your truck bed and may be a hassle if you feel a need to remove it for cleaning very often.



by:

I purchased the tailgate protector. The material is soft and pliable. Unfortunately,the plastic washers that come with it are too small and therefore soon after installation, the protector peeled away from the tailgate at the top where it uses the washers to keep it in place. I ended up using some larger diameter washers to keep it secure. It fits well, and now does a great job of protecting my tailgate.



by:

We received this item in a damaged box that was taped up on one end and busted open on the other end with the mat dirty and warped hanging out of the box. I don't know who to blame the damage on but we are not happy with a damaged product. It is dirty and looks like it may have been used and placed back in the box. I'm expecting this problem to be corrected.



by:

Installation was quick and easy. It fit well and appears to be durable.



by:

Was easy to install. Secured by factory bolts in tailgate. Looks nice no issues.



by:

Up until about a week ago, the bed liner was working just fine, but then the adhesive holding several of the Velcro strips failed or wore out, and the liner caught air and pulled away from the rest of the Velcro and flew out of the bed. I had to pull over to retrieve it from the roadway. I've tried applying some more adhesive, but it still gets air under it, so I had to remove it completely.



by:

Overall the bed liner was easy to install, the fact that it was designed to fit the bed of my specific truck and had a good fit and finish was important to me.
Another nice attribute is that the liner extends up the walls of the bed and does not simply end at the bottom of the bed. This helps keep snow and water and debris away from the bed itself.


The service I received from etrailer was above and beyond and exceeded my expectations.
Jena called me to update me on a change to my order, then followed up twice to let me know the item had shipped.

Highly recommend etrailer !!




by:

Could easily be made better. The material is great but they could improve the interface with the upper lip of the tailgate and include MORE hook and loop. Also, even though it's fairly obvious, they don't mention using the shoulder washers when screwing it down.



by:

It’s very light duty and difficult to clip in. Clips get caught up on any cargo your sliding out .
It looks nice new but not very functional if you use your truck bed.



by:

This product will not install on a tailgate that has a spray on bed liner applied. The mat will not fit under the supplied clips. I drilled out all the holes and just used the existing tailgate hardware to attach it. Poor design by WeatherTech. I recommend etrailer to not carry this product.



by:

The liner is thinner than expected.



by:

It was a perfect fit. I did need to lift the plastic end of the tail-gate, then drill holes for where the tabs go through, thus making the strip they send along unnecessary. I'm thrilled with the way it looks.



by:

La verdad me gustaría regresarlo pero ya lo corté para acomodarlo No vale$ lo que cuesta. [Truthfully I'd like to return it but I already cut it to fit. Not worth the cost]



by:

The Bed Mat is 100% durable in my experience and I re ommend it



by:

Tailgate liner was thinner and more flexible than I anticipated, but the material seems tough. It has held up well to heavy use.



by:

Good fit and holding up well



by:

I pretty much trust everything Weather Tech, but this product missed the mark. It was EXTREMELY difficult to install. It uses a long plastic "C" clip along the upper edge of the tailgate to hold down the mat. You're suppose to install the clip and then slide the mat in from one end, even with lube it wouldn't slide in. I've been working on my own cars for 50 years. It took me quite a while to get the mat into the "C" clip. Then you have to move it back and forth some to line up the screw holes that are reused in the tailgate.



by:

The product does what it's suppose to, protects tailgate from scratches and dings. Looks good and is durable overall. One thing that could be better is the trim/attachment strip at the top. It is a harder plastic that can be caught when sliding something out and gets chipped and broken. Overall the product works as intended.



by:

I was very pleased with this product easy to install , I was able to install it in about 15 minutes. Very light as far as weight on the tailgate which I liked as well. Definitely would recommend this product for protection on your tailgate. Thank you



by:

I’ve used Weather Tech products for years, they are terrific. .



by:

I have been a weathertech fan and these exceeded expectations. Just bought a new 2020 F150 and they were perfect.
