3M Professional Grade Rubberized Undercoating, Corrosion, Water and Salt Spray Resistant, 03584, 16 oz. Aerosol

Good working spray can! You need to make sure everything is well prepped! Warm up the can a bit in broiling water and just go for it in one spray! If ya stop too long the tips will get clogged and you’ll need to unclog the spray nozzle soak in vinegar for 15 minutes get air compress gun to blow out the stuck residue at the sprayer. The texture and thickness is good! I use it to spray my exterior trims of the car and all the weather strips since it’s a waterproof product.

Great item works great

Overall i like this product alot. It wasn't difficult to use, it works well for its designed purpose and is not that expensive. Definitely cheaper than having an undercoat done. I used it on my Jeep Cherokee on the door bottoms to prevent rust that had just started on it that is typical for Cherokees, as well as the fender flares and part of my hatch i did a design on to prevent rust below the window but a black strip would look odd (for reference a 1/16 inch thick coat took 5 cans). What this product is basically is an aerosolized, hardening, tar (meaning like road tar/asphalt). The advantage of this is that it is nearly impossible for it to chip so once applied water will never get in between the coating and rust out the steel. A disadvantage of this compared to say Rhino Liner (a ultra tough hard plastic like coating which I am aware isn't considered an undercoating) is that with enough force a jagged object can scrape it off. However refinish of a scraped off area or scratch line would be a very easy repair with simply another spraying or spraying some in a cup and dabbing it on. So when you purchase this think of it as a midpoint between Rhino Liner and Plasti-Dip (a latex like coating that can be applied and easily peeled off). As far as aesthetics go I really like the look of it, if you spray closer it smoothes out more to a molded plastic like look or if you spray further away from your surface it looks more like a powder coat/bedcoat. However if scraped it exposes that it's not truly black but a very dark brown. Also before spraying on the surface of your project I recommend practicing on a piece of plastic or cardboard, once you get it down its not difficult to apply however if you go to slow you'll get blobs that will not dry properly and look bad. As far as drying time goes between each coat it needs at least a half hour to tack on, then after a few hours it will seem hard to the touch but it's not. At this point it can be touched with your fingers and nothing will happen but if you use your nail some may scrape off. Only after 2-5 days depending on temperature, humidity, and air movement will it achieve its full hardness. That's as much as I can learn anyone about this. Hopefully this helps future buyers of this well made product.

So far I am Very Happy with this rubberized spray on protective product. I mean, it is made by 3M so you can't go wrong with a brand that has been so well established. I have ALWAYS appreciated 3M quality.

Good quality spray, covered well, good price easy to use recommend gloves. Helped with sound deadning.

good paint

"The perfect combo for harsh winter conditions! Living in a snowy area, rust is a constant battle, but spraying the Rust Reformer followed by the 3M Rubberized Undercoating creates an unbeatable protective barrier. Couldn't ask for a better shield against snow and road salt!"

3m c est la qualité, bon spray épai et collant meme sur la rouille.

fait les table de quad tres bien

This product is amazing,easy to apply and it actually feels like rubber.I used one can for my wheel wells and rocker panels.Everything was covered nicely.I would recommend this product to everyone.💯 satisfied.

Can is a one use sorta thing, the rubber will dry and seal up the spray nozzle. It’s great stuff but just annoying if I don’t use the whole can ✌️

Covers well, easy to apply. Be sure to mask off areas that you don’t want product on. If you do get overspray, a cloth with some varsol will remove overspray.
