4 months later holding up nice! Looks professionally done
This worked great and saved a ton of money. Not sure what paying a company to spray your bed goes for but i know at least $1,000 like 10 years ago. Probably double that today. Block out an entire day, wake up early, have lots of rubber gloves, knee pads, sanding gloves (harder tip protection), acetone bottle and some extra rollers, paint trays and brushes cant hurt. I used what came with the can, the sand paper, rollers and brushes and it turned out great but the paint brush and rollers hardened after the first coat. Was able to get 2 coats with one can and had a little left over. They make a spray on bed liner than you can use for touch ups over the years or to get spots you may have missed or better straight lines. My only issues were caused by my impatience, not taping off properly and not anticipating the drips. Even though it is thick, its runny when you first opem the can. If i could go back and do it again, i would have used a wooden spoon or cheap long instrument to scoop the thick grit from the bottom of the can and mixed it in the tray with the rest that i poured out. On my last coating it thickened up substantially with a lot more grit than it initially had. First layer was more clear and runny black like water color paint in some spots but as it dried i went back over it, prior to doing the 2nd coat. I lathered this stuff on THICK as well. However, i have a 2024 Colorado with a 5ft x 5ft bed. Use that info to help you plan better for your ride, maybe youll need a spray can to help you finish out or buy another can. All in all, great product. Cheap and reliable so far. No chipping or cracking and it looks great (when its cleaned😂) i’ve been camping several times, turned the back into a pool on the 4th of July and hauled a ton of furniture, wood and a few dump runs and just took the photos after all that. It looks pristine when its cleaned. Everyone has said it looks professionally done

Chevy s10 longbed, full coverage! Fantastic product
Super great! I’m so happy with it! Looks great, amazing texture and thickness, it adheres extremely strong! I haven’t had any scratches or issues with it either. The texture is very grippy too. My advice! 1. Prep really well, I sanded everything, blew out the debris with a blower and cleaned everything with purple degreaser and then acetone. This step is extremely necessary. 2. Next I opened the can, which was completely normal, not sure why people struggled just remove the clips and use a flathead screw driver. Don’t shake the can, you need to mix it with a paint mixer attachment 3. I found that the rollers broke very easily, so after they broke, I just used the paint brush it came with and I had much better results. I did each layer a day apart due to work, and I did 2 layers. It laid very thick and nice with the brush, and I was able to cover every inch in my Chevy s10 long bed. This bed is about 90 inches or so and i still had some product remaining after a generous thick coat

Phenomenal Product - Some Installation Tips
I put off applying this to my truck, because as others have mentioned, I thought I must be mad to be scuffing my 40K truck to save a few hundred dollars. The truth is my truck originally came with a drop-in liner which I hated, and I really wanted to replace it with something that protected the truck as much as it protected the contents. So there is a video on Herculiner's website that talks about the three easy steps. Let me say that in my case, it wasn't three steps and it wasn't easy. I feel like to do a good job, this application really requires some elbow grease and time. As you can see in my photos, I am extremely happy with the results. Except for a couple of spots where the liner pooled or ran a little, I wouldn't change a thing with the results. However, the installation video and instructions do miss the point a few times. Let me address those: The video and the included scuff pad, insinuate that the scuffing part of the job is a quick, almost trivial step. It is not! It is probably the most important step. I knew that one little scuff pad wasn't going to be enough, and I wasn't brave enough to use an orbital sander or any kind of sandpaper. So I bought a box of 3M Scotch Brite Scuff Pads (https://www.amazon.com/gp/product/B00MBPTH56/), and promptly went through all of them and the included little one in the process. I didn't get down to the primer or anything like that, but I made sure that all surfaces, especially near the back edge, the tail-gate, and the wheel-wells were properly scuffed up. I didn't wash it with soap and water because I didn't have time to wait for it to completely dry. So I blew off all of the paint dust off with an air-hose, wiped it down with rubbing alcohol, and then cleaned it twice with acetone. With humidity in the 70% range and temperature in the 80s, the liner was still very tacky after 4-5 hours, so I let it sit overnight in the garage and applied the 2nd coat after about 14-16 hours. Here is where my installation tips become really important. WEAR A RESPIRATOR! I thought that because I was applying it outside on a breezy day, everything would be OK. Boy was I wrong! That is some strong stuff, and I did not hesitate to wear a proper respirator the next morning with the adequate Vapor Cartridge Filters (https://www.amazon.com/gp/product/B000XBKLLE/). The first coat went on in about 2 hours, and the second coat a little faster. But I definitely felt better after the second coat during which I wore the respirator. Don't make the same mistake I made. Other than the respirator, the other thing you'll probably need is a quality texture roller. I had no issues with the roller on the first coat, but when applying the second coat the plastic roller (the second one included in the kit) began to fall apart almost immediately. It was a pain and a mess having to stop and remove the little bits of plastic that were being left behind by the roller. MY guess is that the very nature of the liner, which is rough and textured, makes the roller disintegrate in the process, which is why the first coat had no issues. So, before you start and have to run to Lowe's or Home Depot mid-project, get yourself something like this roller (https://www.amazon.com/Linzer-RC-119-0900-Texture/dp/B000PSBIF8/), and cut to suit your sized applicator. I know others have mentioned it, but I had no problem with the brush. I discarded it after the first coat, and used another inexpensive one for the second coat. I did remove the tail-gate to make access easier, and honestly I don't think I would want to apply the liner with the tailgate on the truck. One last bit of advice, is to wear double gloves. I was using nitrile gloves but every time I had to change them it was a pain putting the new ones on because my hands were sweaty. On the second day, I started with two gloves on each hand. When I went to change gloves, I just peeled off the top pair, and replaced it with a new set without worrying about sticky hands. The extra work required to scuff the truck, the mandatory respirator, the disintegrating roller, and the additional cure times notwithstanding, I can wholeheartedly say that I love this product and I would use it again if needed.

I’m not a cheap guy, but I decided that I’d give this a shot before taking my truck for a spray in liner at Line X. I ordered the Herculiner kit and received it the next day. I also bought a nylon wheel attachment for my drill for the scuffing process. It took me approx an hour and thirty minutes to scuff the bed and tail gate. Another 15 mins to tape and about 30 minutes to prep and clean the surface. It took about 30 minutes to put the first coat down and it was a really easy process between the roller and brushes. I used a paint mix attachment for the drill and that made mixing super easy. It would have been tough doing it by hand. It took the better part of 6 hours to to get to the point where it didn’t feel tacky, but I wasn’t able to stand on it until approx 8 hours had passed. The second coat went on equally as easy and I let that coat dry overnight. It looks great and is much grittier than the Line X spray liner I had on my last truck. I’m 100% satisfied with this product and my only recommendation would be to find a second similar roller as the first one did begin to break down midway through the second coat. HIGHLY RECCOMEMD!!!

I read several reviews recommending watching application videos before hand and I totally agree with that. Product goes on really well and seems durable, but I’ll have to wait and see. I also recommend wearing gloves and clothes you’re OK with disposing with afterwards. This stuff really doesn’t come off skin or clothing easily. Overall, satisfied with the results and would recommend.

The product was excellent and came out looking great. Be prepared for the glossy finish. Only gave it 4 stars due to the prep time being seriously understated.

If you are going to apply this product i highly recommend watching some videos before you do so!! there are many little things that are worth knowing before you apply product. bought this over a year ago and it sat in the garage.. decided to apply it finally. a couple videos said stir thoroughly, they were under exaggerating i think... you need to stir this stuff a lot. it takes a while by hand but it will mix. Cons: most videos said it takes between 1-4 hours to set or become "not tacky" for your second coat i found it took over 6 hours until it became not tacky. not the end of the world just manage your time accordingly. i was warned but in a video one man explains that this is a polyurethane based paint, which means it sticks to everything. I thought he just meant be careful what it touches... i think he meant to say if you get it on your hands its not coming off for a while... not the end of the world just wear some kind of gloves, just sucks i was to stupid to do so. once you dip your roller in the paint it is very saturated with the product and literally just throws it all over the place unless you very lightly just roll it on. yet again not the end of the world just need to get used to the best way to apply it. Pros: this stuff is awesome. goes on nice and thick after that second coat. really nice texture to it, literally has the texture of a spray in box liner. really durable, maybe not for anything over 5 years but its super easy to re-apply over old liner. everything i have seen says it takes 1 gal. to paint a 6' trucks bed (my gmc is 5'8") i did 3 coats and probably have just over half a can left. maybe i was being stingy but doubtful after doing 3 coats, you could most likely do a 8' box no problem with a 1 gal bucket. this stuff is pretty stupid proof, and will literally roll and stick on anything. i sanded and scuffed up all of my box except for one spot to see if it was any different at all, i cannot tell in the slightest. I am not saying do not prep the surface properly!!! but on the 12"x12" section of my box i left i did not notice any difference in application or finished product. All in this is and incredible product for what you pay. it cost seven or eight times more to take this in and get someone to spray a box liner in. i am super happy with this product and would gladly recommend this to anyone.
