Best over all
This is one of the best products I've ever used. I've used other products before and not had the same results that I've had with this product if you're looking for an affordable product that can give you results that you need and want then I'd recommend using this product over any of the others it's much more affordable and has the same durability as the other pricely products

Works well in car trunk
Use to cover rust treated car trunk areas. EASE OF APPLICATION: I used a paint brush. Be sure to use gloves FUMES: Although it's water based, it does have a slight ammonia smell. I used a mask to help. Also took frequent breaks because I was in the trunk applying it DRIES QUICKLY: As with most paint, dry speed depends on ambient temperature and humidity COLOR VARIETY: Not a concern since used in the trunk. Black is fine EASE OF CLEANUP: Water based so it was easy to clean with soap and water. COVERAGE / QUANTITY: I used one coat. I have around half the quart left. I'll probably use the rest as a second coat where water may hit the most, e.g. at bottom areas. FINISHED PRODUCT: It has a hard, not rubberized, finish with a textured feel. IDK what the textured bits are made of. It's nice to see. I used one coat. I presume multiple coats will still be a hard finish, not rubberized. WORKS WELL: As of 9/26/25, It's been around one month since application. So far, so good. I'll get more to use for my brake lines

Wear a mask, strong paint odor.
This paint is awesome. Goes on thick, cures in 24hrs, and good to go. Bed looks brand new. Also used it on some treated wood for outdoor application.

Not Bad..
Pros: Somewhat self-leveling after rolling out, applies well, easy cleanup on skin. Cons: Doubt the long-term durability, probably needs two coats for best protection. This isn't like Herculiner, in that it has rubber granules within for traction and a slight sacrificial wear layer. This is more a rubberized coat that seems to derive traction from the inherent grippy texture. So I'm just guessing, but from the feel of the product, it's not going to be as durable as Herculiner. You get it on your skin, and you can roll or peel the rubbery coating off, easily. That said, the amount a quart covers seems to track with the estimation of 40 s/f. I covered a small trailer's interior (5.5'L X 4.5'W X 10" sides/tailgate) with it. After rolling it out, it will reconstitute a wet surface that tends to hide streaks. Using a open-cell foam roller for bedliner application produces more a "grained" surface like old cameras. And that's fine; it's overall a nice look that will hide any minor surface flaws. It works well with a brush to get in the corners, also.

Easy to apply and makes you look like a pro
I used this truck bed coating on book shelves that I intend to use outdoor to store electrical components inside. I was expecting this to stick to the slippery plastic on the exterior walls of the wooden bookshelf and it worked out perfectly. The coating protects the wood from the elements and helps to somewhat waterproof the wood, which is exactly what I wanted. I can see this coating working perfectly on metals such as a truck bed. I applied it using the roller method and results look very good. Easy to use and apply. Any mistakes are forgiving because before it truly hardens its like a peelable rubber material. A great overall product.

Salvaged tools and cameras where no replacement parts available
This is great stuff for another purpose. I have power tools and cameras whose rubber coating became torn or sticky. I removed the damaged rubber from tools and coated the bare plastic with several coats. Good as new and even more aggressive grip than original rubber. For sticky rubber I just coated on top and it works great.

Only For Looks Not Function
The product itself looks pretty good, but it doesn't seem to be an actual bed liner, more like a fancy rubber coating. It has been over 24 hours since application and anything rougher than human skin will damage the finish. I set an item about 10 pounds with rubber feet on the finish, and it couldn't handle it. I will give it 1 week to know for sure if this is a dud but so far I cannot image this finish holding up to anything a truck bed is used for. I applied about 3 coats of this to get it on the thicker side, and I sanded then cleaned everything prior to applying the coating. Adhesion seems to be strong, it is just durability that is seriously lacking.

4年前の以前2液性の商品は強靭な塗膜でカチカチでしたが、改良した今回の水性ベースはラバー寄りの柔らかい肌みで爪でカリカリしたら細かく汚く剥がれます。 商品説明の強靭な塗膜とか石でも大丈夫とか東スポみたいな説明文は大間違いです!!
