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

Absolutely love this product, I've used it on my Hummer, Samurai and my Silverado and it looks great, easy to apply and is durable!!!

is what we expected. No complaints

This has a great amount of coverage and fills in small gaps very nicely. It even came with more in the can than the last brand I bought and that other one was thinner and couldn't fill the gaps like this one does. I immediately bought more cans as soon as I used the two I bought. If you're trying to coat the bottom of your car or truck I'd strongly recommend five or six cans.

1 can = 1 wheel well = 1 1/2 layers.It's good stuff, but you need lots of cans if you want to do more than 2 layers per wheel well. Do the math.

Great stuff!used for my fender wells , and I’m impressed! WEAR A MASK WHEN USING . THIS STUFF IS STRONG!

Few weeks in and it’s held up.

I know this is supposed to be UNDERcoating, but I used it OVER instead. I wanted rubber texture for various hand tools, yet did not want to spend $60-$100 for a good set of cushion gripped screwdrivers and such.So I set out to find a way to apply decent grip to a tool without ruining it or adding excessive bulk, like with some grip tapes. My first test piece was a wooden handle to a sink plunger that was collecting dust. To judge the adhesion quality, I did not roughen or prep the surface in any way besides wiping with a wet cloth to remove the dust.I carefully sprayed a small amount on opposing sides of a 6 inch end-section of the handle, spreading it with a small paint brush. After I was satisfied with the applied thickness, I began to stipple the surface with the tip of the brush for texture.After 24 hours of set time I tested the surface for results, and was happy with the results. The texture provided good traction without noticeable bulk, as the coat was barely thick enough to hide the wood handle color. I then began to twist the grip in my hand with light-firm grip pressure, trying to rub off the surface, and had very little specs of texture come loose. I accounted for stippling surface rise, lack of surface prep and amount applied, and felt the makeshift grip was more than adequate.Next, my guinea-pig-screwdrivers: A USA made Craftsman set I got on Black Friday a few years back, which were very cheap so I would not curse the sky if I were to ruin them. The handles have parallel panels, all of which are smooth plastic. I lightly roughened every other panel with sandpaper, cleaned off the dust and applied the same way. I varied the design on 3 different screwdrivers for fun, yet they all work just the same. They are still holding the grip after MUCH use, from automotive to normal building construction use. I plan on doing a few more when I can get in the garage.Note: Take precaution for over-spray because this stuff can be messy. Also, when sprayed at close proximity it tends to bubble on the applied surface. Lastly, I do like this product for more stationary grips, but don't believe it will hold long on something equal to a baseball bat grip. If somebody tries that, please let me know how it turns out on that kind of aggressive surface.

Goes on easy, nice coverage, very adhesive to surface-look great!
