3M - 03584-6PK Professional Grade Rubberized Undercoating, 03584, 16 oz

Very good quality

I don't get as much coverage from these as I had expected but they do spray really well and the finish seems to be great. As with the majority of the 3M products I use I am happy with the performance.

It feels like this can sprays stronger than most aerosols. The spray shoots further, making it easier to get to hard-to-reach areas. During the initial part of the spray job (until about 1/2 full) you can rotate the can in any direction and it will still spray. Once the can is getting low, it will only spray the contents when it is held upright. That's why some people say it won't spray upside down (but it really depends how full the can is).The results look professional because this product creates an even distribution of material on the surface with a nice texture. It takes about 2 cases (12 cans) to complete a full size car. There's really no special trick to this, it's as easy as using a can of spray paint.Be sure to wear eye protection and disposable clothing. The orange pumice hand cleaners will remove it from skin with some scrubbing.

Stuff works, basically tar in a can, warnings: Use in a very well ventilated area, use outside your vehicle only, mask of areas you don't want to be cleaning tar off of later, plan to use the whole can in one shot.Used to coat the flimsy plastic wheel arches on my Ford Focus, cleaned the surfaces first, sprays on like thick paint, fairly accurate spray pattern, will get you high so use outside!, tar residue takes 3-4 days to fully cure but can be handled (carefully) after 45 minutes or so.

Used this on my 2004 Honda Accord and although it is messy it goes on very well, adheres very well and doesn't smell once dried. I would use a drop cloth next time to avoid having to clean my floors but lesson learned.

I purchased a 6 pack for coating the underside of a 2007 F-350 8ft truck bed. It goes on very quickly and very nice. I went through all 6 cans in like 15-20min. A 6 pack did maybe 3/4 of one coat. I am not sure it will need more than one coat, but I am getting another 6 pack. Seems heavy duty and while I am slightly disappointed in how much I have to use, I am super impressed by the quality and speed of application. You might get the entire underside of an 8ft bed if you are a little more careful than I was.

Don’t spay on surfaces subject to oil/fluid exposure. We applied it to a transmission crossmember and everywhere fluid leaks onto, the 3M product dissolves and rubs off. It can withstand water but that’s it.

This product works really well, I read reviews of this being among the top products and I definitely see why. One thing is that it does take a lot of cans to paint. I got a Ford truck and it took me 8 cans just to paint frame and suspension one coat.
