Dynamat Dynaroller: Rubber Roller Tool for Applying Sound Deadening and Car & Home Insulation Material – Achieve Professional-Looking Results with No Air Bubbles – Made in The USA

I just had to leave a review of this roller. I LOVE this roller. Don't be confused, I'm not talking "sorta-like" I'm talking "BFF - lets move in together". Lets start with the business end - the roller. Like most, if not all rollers, this roller rolls. The gray part rotates freely in a forward direction and with the application of a different muscle group in the arm, will actually rotate freely in the revere direction as well! - I know - weird, right? but super useful. I estimated the rolling resistance coefficient to be within norms for a roller of this size but when I bench-marked it against leading rollers, it actually did better by a factor of 6-8% - MIND-BLOWN. The handle is made from a nice wood, no doubt a green-grown renewable forest lumber.It did the job - Dynamat install. The handle is perhaps a tad small really, but workable. The metal roller attachment points on both sides do stick out a bit, so getting to some edges was more difficult, but again, not overly burdensome. I'd have preferred a roller with a pin to one side only - like a paint roller. Otherwise, it seems quite robust.

Used with Dynamat Extreme installation. There are probably cheaper versions of this tool out there, but I didn't spend much time researching those. This roller works very well. I used it for a complete install of Dynamat Extreme Trunk Kit (5 large sheets) for four doors and the trunk. I like the solid wood handle, the bottom end of which can be used to rub in some of the tight areas with creases. The rubber roller is consists of very firm rubber so it allows you to apply a lot of pressure to get a good seal. Despite a lot of rolling with heavy pressure, the axle did not bend or fail in any way. The length and width of this tool is just small enough to allow you to get into many tight spaces. This is a well made tool and should get you through many applications if you do this job on multiple vehicles. You may need to use your fingers for finishing off the edges of Dynamat in areas where you can't reach with the tool - be sure to wear gloves when you do so as Dynamat edges are sharp aluminum. I used leather yard gloves and they worked great.

Works as advertised. The tool is small which allows you to get it into smaller places. The roller is a stiff smooth rubber that won't damage paint or anything. You can use the roller to push dynamat/dynaliner flat and uniform. If you angle the side of the roller to just get the edge the rubber will squish and allow more pressure to be put down on corners and what not. The wooden handle can also be used to apply a lot of pressure in a small area. If there is something hard to reach (i.e. inner door skin) you can turn it around and try your best to squish it down. Otherwise corners, dishes, or rounded areas the handle can push the material down much better than the roller part and conform it to the panel.If you are in a tight budget you do not need this tool. Any smooth rounded tool/item can be used to push the material down. The roller just makes the job easier as it pushes the material down in a large area quickly.

I bought this along with the Dynamat tape in a combination order from the Amazon seller. Then I misplaced it and went searching all through the garage and house. Finally, I decided that I would just go ahead, install the Dynamat and devise another solution for pressing the mat down. I came up with an old tennis ball and it worked BEAUTIFULLY! For getting the material into smaller spaces, the round of a screwdriver worked very well. After I had done the floors and above the headliner, I found the roller.So, I'm giving this tool four stars because I wanted mat material on the inside of my doors and this tool is very good for reaching up inside the door and getting beyond where my fingers can reach. However, if I had not chosen to put mat in those hard to reach areas, this tool would have been completely unnecessary.The tool is quite small and it is very well made. So those YouTube videos that show guys using cheaper versions from the Dollar store or Harbor Freight are using lighter duty rollers that are larger in size and may not fit up into the inside of the doors. You'll have to decide for yourself.So, the bottom line is that, if you are a professional and do a lot of Dynamat applications for customers, this tool will be invaluable, it's tough strong and will last for years. However, if you are a Do-it-yourselfer like I am, no so much.
