Nice texture and adhesion
The box had been opened and taped shut on one end. All can were dented up but the hike clips were still on and the lids were secure. First can was fine, havn't opened the others yet. Used a drill mixer to make sure this was blended well. Paint is very thick compared to regular paint and goes on easily (be sure to prep the surface properly) Covered perfectly with 2 coats but did one more with a textured roller just to be sure. I used a brush for most of my project due to having a lot of corners and small spaces. Paint self levels a bit. DO NOT GO BACK OVER WET PAINT... IT WILL BUNCH UP. LET IT DRY AT LEAST AN HOUR. Sand any bumps, drips, and "high traffic"areas between coats. 70 degrees and 50% humidity, first coat dried solid in about 3 hours.... touchable in about an hour. 2nd coat wasn't totally dry for 4 hours but was also touchable in a little over an hour. Texture and color is consistent.

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.

Works Great Good Price
I used this to protect the undercarriage of our RV. I had some bad luck with Rust-Oleum spray cans of undercoating, it kept clogging, but this roll-on version worked great. I used a a cheap disposable roller and stored it in a plastic bad between coats and was able to use it several times. It dried super fast on a warm summer day. The finished product has been reliable and has a nice hard and matte finish.

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.

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.

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!!
