HushMat and Dynamat have been rivals for many years. They are both really committed brands delivering effective results. They also have a “Ready to Install” range that boasts fittings of 350k different makes and models. This suits some people but obviously is expensive compared to their other products. Then there is the question of quality. In the end, both of these products deliver on quality with marginal differences between the two.

Hushmat and Dynamat are both reputable sound deadening brands. In this post, I’ll share with you the findings of my research. This will hopefully help you in deciding which product will fit your particular application.

HushMat

HushMat is another industry leader. They’ve helped provide new cars with the luxury of a cool silent drive. Of course, there are a dozen other methods they use, including ANC, inlaid door designs, triple seals, etc. However, damping is still a critical component in this endeavor, and HushMat is one of the best brands.

HushMat was introduced to automobile manufacturers in 1988 and was approved by General Motors and Chrysler for in vehicle production. They are one of the only companies that manufacture their own sound deadening and are specified for every automobile manufacturer in the United States, Canada, and Mexico.

HushMat Ultra is one of the only OEM Spec approved damping materials available to the automotive do-it-yourself market. A simple “peel and stick” application treats the firewall, floor, tunnel, doors, trunk, trunk lid, quarter panels, roof, and hood.

Their advanced product technology requires no (or very little) surface preparation other than a little cleaning. No need for acetone or alcohol rub down. This reduces the installation time by half. The product’s unique properties allow for installation using only two basic tools—hands and scissors. A roller is highly recommended, though.

HushMat Ultra is rated to perform up to 400 degrees Fahrenheit and adhesion is guaranteed. Silencer Megabond is rated to perform up to 300 degrees Fahrenheit. The material is designed to perform and maintain its flexibility at a wide temperature range of minus 30 to 400 degrees Fahrenheit.

Dynamat

Choosing Dynamat isn’t just about picking a sound deadening product; it’s an investment in unparalleled noise control and vehicle comfort that stands the test of time. As a DIY enthusiast keen on effective solutions, you’ll appreciate Dynamat’s industry-standard quality, recognized by leading auto rebuilders. It’s a one-time setup with no future fuss needed – think of it as a decade-long peace and quiet guarantee for your ride.

Yes, at around $5 per square foot, Dynamat isn’t the cheapest option out there. However, its exceptional sound dampening abilities justify the cost. For areas needing heat insulation like firewalls and headlines, the thicker, slightly pricier products are your go-to, adept at quelling those low-frequency rumbles from your vehicle’s rear.

Dynamat’s technology evolution has slightly pushed its price upwards, a small price for the significant advancements in noise control it offers. The Superlite range presents a more budget-friendly alternative for extensive projects without compromising on quality. This range, while thinner, covers a larger area, making it ideal for vehicle floors or as an additional layer where needed.

Installation is a breeze. The Dynamat Xtreme version, with its butyl rubber and aluminum makeup, contours effortlessly to any vehicle surface, ensuring a snug fit without the hassle of odors or mess. No special tools are required, just your hands and a bit of patience. The result? A significantly quieter, more enjoyable drive, proving Dynamat’s worth as an investment in your vehicle’s performance and your comfort.

What to do next

I’ve detailed the application process for sound-deadening materials. If you’ve already decided on where you want to apply it see my comprehensive guidelines for

If you’re not sure where to start, I strongly recommend you begin with the doors. From there, you can move on to the trunk.

What you’ll need

A panel removal tool kit is required for the panel pins. This is because they avoid breakage of the pins during the removal of them. It’s also useful for prying away the panels without doing damage to your vehicle’s paint job.

Aluminum tape is also needed. You can patch up the parts where there might be gaps left or use the tape to give your application a clean finish.

Wear a good pair of workman’s gloves while working with the material. The foil edges are sharp and cut through your skin. The glue is also best avoided.

You can use metal shears instead of scissors for products like Dynamat and others. You can also use a switchblade.

Use the correct seam sealer (if required) to avoid it setting and causing ripples on your trunk lid. In addition, the seam sealer should maintain some flex when dries.

You may want to get a set of additional Bumper Retainer Clips, just in case you damage some or if you find a few missing already.

Use a portable light system to make it easier for you to see.

On these other blogs, I’ve provided a guide to purchasing the right pack size for whatever project you plan on undertaking. The step-by-step guide walks you through the process, including application.

You should check your car’s manual first. For around $20, you can find a detailed version. The easiest way to find the hard copy repair manual for your vehicle is to select Repair Manuals by Make and Model. Or you can get an electronic version. They both have all sorts of instructions and guides, whether it’s for customization, maintenance, repair, or even simply just learning about the inner workings of a particular vehicle.

Conclusion

As I mentioned before, depending on your application requirements, either of these products will produce results. Dynamat offers a greater product range which gives you flexibility and allows you to budget better and reduce wastage.

Good luck and happy soundproofing!
