    I have a truck that I use for off roading & I wanted to protect it from rust & such. After looking around for a while I chose Al’s truck bed liner & couldn’t be happier. Easy to apply, mixed well with the pigment that I chose, and is nearly indestructible.

    There’s another reviewer that suggests a mask, I’m seconding that. Very strong fumes from this stuff, even in a well ventilated area. I did it outside & still think this is necessary. (Pro tip: make sure to weigh down & tape your drop cloth to avoid messes. this stuff really doesn’t come off of surfaces.)

    I’ve painted many items with Al’s liner and its durability impresses me every time. I have also mixed other automotive tints in it for when I painted my Jeep OD Green. I love coating cars and speaker boxes with the stuff, it really toughens them up and I never have to really worry about damage from off roading or things being thrown in the truck against my sub box. It also seems to be a bit quieter in the cab of my gen 1 4Runner.

    The only downsides of this product are it’s initial smell, a chemical respirator is a necessity, and the fact the once it gets on your skin it is pretty difficult to remove. I would strongly recommend a box of cheap Nitrile gloves. Prep is important for adhesion. A wire brush is a bit too rough. I recently got a nylon filament cup brush and it took a lot of the effort out of proper prep.

    GREAT PRODUCT, 1 kit was not enough for me to do my nissan titan shortbed, i had to buy 2 kits. $365 spent with everything, had to tape truck off twice cuz i ran out with the first kit. Superior product to any other DIY kits. Looks just like scorpion liner. I bought all their stuff, inital cost was expensive, but now I can do other projects with it, just have to buy materials. 4 stars because 1 gal wasnt enough. Needed 1.25 – 1.5 gal. You can easily change the texture of the product with air pressure and supplied nozzle with the gun. I gave mine a rougher texture than the image on Als Liner Website. So far it still looks wet, nice shiny gloss to the finish. Hopefully it will not fade.

    I recently purchased a total of 3 gallons of Al’s liner and have been very
    pleased with the product and the customer service. Make sure you do not over mix the product and if you have questions call them, they are very helpful. It is a great DIY product that gives you pro results.

    You can’t go wrong with Al’s Liner. Used it for for over 6 months now on many projects. I recommend you use the spray gun for the best results. No matter what color pigment you use this stuff is consistent with texture, durability and protection. I highly recommend this to anyone who wants a bedliner without the high cost of the Big Box name. UV protection beats the “Big Guys” Al’s wont fade for a long time if ever. Try it, you’ll love it.

    This is definitely the way to go! I have had many people where I got it done and if it was Line X or Rhino. When I tell them I did it with Al’s Liner and their spray gun they are amazed. Excellent product.

    I used it to paint the inside of a Locost 7 style car. Looks good and should last for years. Just follow the mixing instruction perfectly, you really have to mix the crap put of it, or it will separate, that is what happened with my test batch. For the following batches I used an electric drill not a cordless drill and mixed it for quite a while, until the mixture was very consistent and non on the white component could be seen, then it worked great. The fumes are bad so you should wear a respirator or at least apply it outside.

    I bought it to use as an undercoating on a restoration project. The multi-part kits are always better than the single can systems in most stores. Only downside is it’s messy to clean up, no water here. It’s also thinner than you might think. I used a hopper gun (not theirs, a similar but cheaper one from the local HF store), and it worked OK, just use the smaller nozzle with it.

    Make sure you mask off everything you don’t want covered, the overspray with the hopper gun is bad and tends to go places you don’t expect, like surfaces surrounding the thing you’re coating. My first coat was a little thin and a little too heavy, so it wanted to drip from vertical surfaces. A thinner coat would have been better, also watch the shadow lines, still finding areas I didn’t coat as well as I thought. Might want to hold a little back to mix up for touch-up areas later. The hopper gun is big and made it tricky to get into some areas, so again, using a brush or similar for those areas before spraying the rest is a good move, but a truck bed is more open then the bottom of a truck cab so it may not be as big an issue.

    Takes a while to set up as it seemed soft for the better part of a day, but after a few days of curing it’s really hard. Had to use a razor blade to cut out some of the masked over openings in the floor. All in all I’m happy with it so far, only time will tell how it holds up as an undercoating.

    Didnt want to write a review till after i came back from the off road park. I lined my fenders, bumpers, mirrors, & wheels. Nothing chiped off so im satisfied. My truck is stock so i stayed on green trails. Nothing real rocky. I didnt do any rock crawling but it held up to the rocky mud & through trees and bushes. My paint on the other hand is a diff story. Haha! I may line the whole truck later.

    Can’t think of a reason to dock a star. Rolled two thick coats onto a 5×5 tonneau cover, it cured in 30* weather (but took several days, natch), still have half the product in the box waiting for something else to do with it. No complaints at all, it’s great stuff at a great price and I’ll buy it again.

    Went on easy. Just don’t put all the material in the Al’s spray hopper at once or it will drip with your spray movements! We will see how it holds up

    Great stuff BUT, before you spray tape and paper things off. It makes a mess. Overspray everywhere. Wear gloves. It don’t come off your hands or skin. Spilled a bunch out of hopper right to begin with. Sprayed a jon boat, turned out great except for the spill. Wear some type of respirator/filter mask. Now that I know what to expect and how to spray it I will be using more of it

    Third time using Al’s. All three times I used it for body panel coverage (all over bed liner paint jobs) when using their gun you can lay a nice semi gloss textured finish. Absolutely love the product.

    The product was as described. I sprayed the entire inside of my GMC Savana the results were as expected from all the reviews and advise given via Amazon answers. I can’t believe how durable it is. The liner was about a week old and I loaded a 3000lb pallet into my van and pushed it in and it did not give.

    If you have a compressor, you can save a $1000,00+. It really is as easy as their video shows it to be. Line-X in town wanted $1600.00 to do my 12′ box truck floor and 12″ of lower wall, it took me 2 kits worth of material to get the thickness I wanted.

    those people who had runs and problems didn’t mix it correctly or look at AL’s website for more mixing and spraying information.
    I have a 1989 Ford bronco that the roof rails rusted and i had to cutout and weld in new metal. prepped it like i was going to paint.
    I used and slightly higher air pressure setting than AL’s recommended 35 psi spec and i used 60 to 50 psi. when my tank was full it was 60psi when compressor was running and tank low it was 50 psi
    then I fallowed Al’s bedliner instructions and it covered very good and even covered small miss-match areas where new to old metal was welded in.

    LOVE this stuff!

    Used it to line the OUTSIDE of my 4×4 and five years later its still tough as nails. Used the HF texture gun to apply it and had great results, just make sure to spray a mold release agent on the gun if you’re planning on using it again. Once mixed give it 5 minutes to cook before spraying or you’ll have some issues with running. Take your time in prep as well for best results, took me 5 times longer prepping the job than spraying it but it pays off in the end.

    There are other names out there that cost more but basically poly liner is all the same, Al’s has been around longer than most of them without the fancy names and boxes, do yourself a favor as save some money!

    I LOVE IT! I’ve used Herculiner, Rhino Liner, and Lizard Skin and this stuff is the best HANDS DOWN! It’s a 4 part system you have to mix, and that’s a slight pain, but it sprays on clean and doesn’t run at all. It dries in about 2 hours, and then is all done in 24 hours. I sprayed the inside of my Jeep, then liked it so much I sprayed the outside of the Jeep, then the wheels. It’s impossible to get off (I spilled some and tried to remove it) after it dries, but cleans up nicely with gasoline when wet.
    Get Al’s aerosol sprayer, and the mold release for cleanup.

    Product worked very well on wood. I used the rubber bits to reduce slipperiness but they are pretty coarse. Would recommend silica sand instead. Applied with a roller and went on well. Hope that it holds up in the weather

    Easy to spray, sticks well and can build if needed

    I have sprayed many different brands of bedliner in all sorts if places. This one works well and is much better than some I have tried from local stores.

    Follow the directions for surface prep and apply the coating how you choose. You really can’t screw up application unless you don’t clean the surface.

    Grab some you won’t be disappointed

    I had two applications for this one a corrugated steel roof on my back porch entrance. The second was the gate to my back fence. The first application was easy, it dried nicely and gave a textured look to previously bare metal. The other application was a bit trickier. My back fence has a gate that opens to the ditch in back along a busy street. Aside from the wood around there always being somewhat damp when it rains, and pooling in the drive that takes even longer to drain off under the fence, I have water issues. Specifically, wood even treated wood rotting. A few years back I replaced several boards in the fence and have even considered replacing the whole thing with vinyl. The boards are cheap, but the gate is another story. I cleaned it with a spinning water brush, and then a wire brush to scrape off some of the loose grime. I taped off the rest of the fence with plastic and duct tape, and then sprayed down the inside and outside with this liner kit. After it dried, I hit it with the hose and watched the water just fall off. It seems like a better solution than the spray sealer I used on the ground line for the fence posts. Looks a lot better too, but it does stand out from the rest of the fence now. Still, I have not desire to spend 300 dollars on sealing stain and a lot of labor for the rest, so it will just have to look weathered.

    I didn’t have a truck to put his on, but I found some good waterproofing applications, and tried this. I have one more job for the near future, I’m going to apply a thick coat to make a perma bra for my Cadillac. I need some more information, and want to put it in the garage when I do it so the wind doesn’t spray this all over like when I did the fence. Pretty good quality stuff, did not know it worked so well on wood. Recommended, for the do it yourselfer.

    I used this to coat the plywood on my one wheel trailer. I used the roll on method. I read the directions a few times prior to starting my project. I had all the tools I needed and I had the trailer ready to paint before starting. I referred to the directions several times during the mixing/waiting process. I was able to roll the liner on very quickly when it was time, so I did not experience any hardening problems. I also used a disposable roller and container so cleanup was a breeze. Good product so far.

    We selected this kit to spray a 1989 Toyota 4Runner bed. The instructions were very easy to understand and you can also reference the manufacture’s website. Mixing the bottles was easy to do. The most work comes from prepping your area and parts that will not be sprayed. We are very happy with the results and it looks like it was professionally done.

    Used a cheap HF drywall texture gun ,. Did a shortbed silverado 6.5′ and a toolbox , Bought two kits.

    If i were to do it again i would start with the smallest tip base it in without the rubber crumb. Then spray a second coat with the crumb and medium tip. I like agressive texture and just a bit of the crumb goes a long way!

    But overall i am very pleased and seems very tough. We sanded the bed’s flat spots with a 36 grit sander disc on angle grinder then sanded everything else with 80 grit

    Degreased wth lacquer thinner. Then sprayed it all with bulldog adhesion promoter and shot it.

    Make sure you tape up tail light bolt holes as it will blow trough but wax and grease remover took it off

    All told less that $200 invested
