Herculiner, Black Aerosol Spray

I preceded use of this product by trying the rustoleum brand spraycan bedliner, suffice to say the product quality and performance was beyond awful.That experience was a complete was a complete disaster, so I had a good comparison point. To begin this product was fresh in the rattle can and mixed relatively easily. The product appears to be under a higher pressure than regular spray paint, so nozzle effort and strength of the spray streak are noticeably higher. These leads to my first observation that due to the higher pressure, and the relative close focused spray pattern, it takes a bit of effort not to deposit too much material, which can lead to a run, and it also makes getting a uniform appearnnce as to the gloss of the final finish. The product would be better served with a nozzle that produced something similar to the fan pattern of a spray guy. That would facilitate getting more even coverage, especially on the final coat. I was coating a part for appearance, so this was more important to me. I managed to get an acceptable result but it was a little too touch and go for my taste. Obviously the spay gun applied method would solve these 2 problems, but I just had a dashboard to cover. The texture is prominent and even, and the finish is much closer to gloss than flat, a true semi-gloss, or semi-matte finish would be nice as an option. The product dries quickly and looks very good with the above caveats. Certainly it was like night and day as regards comparison to the Rustoleum product; this Herculiner allowed me to realize what I had envisioned for the restoration of an old series 3 Land Rover dash pad. I would recommend this product

nice finish. did almost zero prep work and didn’t even take the steps off or mask off just sprayed it on the truck. any overspray on the truck wiped off easily. they are truck steps designed to get used and stepped on so i am expecting to retouch over time but one can is plenty to do several coats. time will tell how well it holds up but i’m happy with the initial results.

I had previously used Rustoleum bed liner for my mudflaps, cowl, and running board inserts and unfortunately it failed pretty miserably. There was a lot of fading and flaking and it just looked awful. Moreover, it took a lot of product. It was over a decade ago but I seem to remember 10 - 12 cans. The failures have been around about a year into the application. In fairness, some could have been my process which I tried to rectify when using Herculiner this weekend. First, I scrubbed the parts with Sem Soap and power washed, washed with Sem Soap again, sanded, then sprayed down with 90% Rubbing Alcohol and blow off with a compressor. There was still some of the old bedliner on some of the parts but was advised (by AI so hopefully it wasn't wrong) to use Sem Plastic Adhesion Promoter on the parts which were bare plastic so I did that. I then did several thin coats of Herculiner (waiting 10 min between coats as it was a dry, warm day). After the last coat I waited an hour and top coated with Sem Ultra Trim Black. My reason for top coating was to hopefully to prevent UV fading. The coverage of this stuff is nothing short of amazing. For all the same parts I only used 3 cans! It goes on thick so adjust your speed accordingly. I gave the parts a full 36 hours to cure before mounting them back on the truck. The finish is awesome. Nice semi-gloss and textured. The Rustoleum seemed to be more like sand paper which would trap all kinds of dirt. Herculiner leaves a smoother finish, though some of that could be my Sem top coat. I wish I took before pics but you can see the after pics here. Any imperfections were a result of my cramped spray "tent" but if I had the parts laid out and didn't care about overspray I would have done a better job. Still, they look a million times better than previous. Hopefully the Herculiner will be more durable than the other bedliner, but right away the finished product looks so much better than the Rustolem.

Works good looks good but cans keep clogging.

Another excellent product from J B Weld! I did by 2005 Silverado L33 And the bed looks brand new. This stuff is very durable and easy to apply without any problems. A clean dry truck bed and a warm sunny day will give you excellent results! It is well worth the money.

This stuff is great and for the money you cant beat it. I’ve used multiple type of bed liner spray and by far this is the best one. Thick and glossy finish. Covered the whole bed with two cans. Ram 1500

Used a couple cans of these to repair my saddlebags. It sprays well, I never had any clogging, the color looks great, its sticks well, doesn't scratch off easily once it's finally cured. I will warn anyone using this stuff in colder temps to be prepared for extended drying times. It can be done but you'll need a well ventilated space that you can keep warm. If you can't prep those two things then you're best bet is to wait for warmer weather or else you'll be waiting a week or longer for it to fully cure.

I was really disappointed with this product. Out of five cans, three wouldn’t spray at all. I even tried switching out the nozzles, but they clearly lacked enough internal pressure to work. The two that did spray clogged almost instantly, within minutes of use, even after shaking thoroughly and spraying upright as directed. The product itself might have decent texture and coverage (claimed 6–7 sq ft), but it's worthless if it won’t come out of the can. I couldn't return the faulty cans either, which makes this a costly mistake I won’t repeat. This was meant for a light truck bed touch-up job, and now I’m left with unfinished work and wasted money. I can’t recommend this product based on my experience. Q&A Section: Q: How is the coverage if the can actually works? A: Each can is supposed to cover 6–7 square feet, but I couldn’t verify that fully. The two that did spray gave decent texture, but clogging made it impossible to apply consistently. Q: Did you follow the prep instructions (cleaning, shaking, spraying upright)? A: Yes, I thoroughly cleaned the surface and followed all prep instructions. Still had major spray and clogging issues. Q: Can you return defective cans to the manufacturer? A: No, they do not accept returns, which is part of why I won’t buy this again. Q: Would this be good for smaller jobs like fender liners or bumpers? A: Only if you’re willing to risk some cans not working at all. I wouldn’t trust it for anything critical.

This was a super easy thing to do. I used it to recover my AMP running boards and it looks great

Absolutely worthless bought two cans and they were both defected I wouldn’t recommend it tbh

Put this on my new holiday trailer as the paint the manufacturers use may as well be water, they are super cheap. So I lightly sanded the entire front of my trailer, taped everything off and used this [no primer needed], and the results are excellent. This is pretty tough stuff and with proper prep work, will last far longer than the super cheap paint used by the OEM's. I did have a bit of sputtering from the nozzle half way through the project but I stopped right away, cleaned the nozzle and reshook the can with no issues afterwards, coulda just been some gunk. No other issues, no runs, etc. I let it bake in the sun when I was done but that has no bearing on the product. I kinda wish it came in a larger aerosol can but the product inside is excellent.

Fonctionne très bien, il faut nettoyer la buse après chaque usage. Utilisé pour jante OEM, application de trois couches de Herculiner. Il faut bien laisser sècher entre chaque couches. Jai fais un hiver avec les jantes peinturés, aucunes égratignures ou autres jusqu'à maintenant. Parfait!

I tried the Hercules bed liner spray, and while it’s decent, it’s not thick enough for a proper bed liner unless you buy at least half a dozen cans and apply 3-4 coats. It’s more suited for smaller projects. I ended up using it on my truck’s wheel wells and it worked well for that. Just keep in mind it’s better for touch-ups or smaller areas, not heavy-duty applications.
