Tape made by Dynamat

Crutchfield Customer Review (What's this?)

My rating of three stars comes from what you get for the price. 10 feet of aluminum tape. More bang for your buck buying aluminum tape from a maker other than Dynamat. But, if you want the Dynamat name on there to finish up your Dynamat job on your car or truck, it does look nice. Looks good holding down wires and covering seams between sheets of actual Dynamat.

Pros: Looks good.

Cons: You don't get much tape for your money.

A heavenly roll of magic!

If you are experiencing any rattles and it happens to be a pestering screw in your door, DYNATAPE IT! If you are installing dynamat and realized after your install and after its all gone you missed a spot, DYNATAPE IT! DYNATAPE IT till its all out, then buy another roll.

Pros: usefulness, its ductape but for car audio, not in a silly do it yourself-er tho.

Cons: it isn't as thick i thought it would be, but im sure most people are using it for taping wires down that may rattle or something

Crutchfield Customer Review (What's this?)

no actual dynamat on this tape in case you didnt already notice. great stuff to have around the shop. very sticky. great for wires.

Pros: thin aluminum, very adaptable/formable.

Cons: dont know if it would be practical, but i'd kindof like to try some tape with actual dynamat attached also.

This product would be great if you were leaving the Dynamat Xtreme exposed. You can cover the seems. Hence the finishing tape. Makes the panel look like one full custom sheet size. If you covering with Dynaliner (like I was) it's kind of a waste of your money.

Pros: Custom look

Cons: 30 feet isn't very long.

Not quite what i expected.

Written by: Thought it was just like fact it is ju from Warren, CT on October 10, 2013

I kind of thought this was just like Dynomat, but when i received it, it turns out to just be more pricey Aluminum Duct tape. I suppose you are kind of paying for the outside labeling here really.

Pros: Nice Dynomat Lettering on outside

Cons: Same stuff at the hardware store only for less, less the Dynomat lettering

Not what I expected

Crutchfield Customer Review (What's this?)

Beware, this is not a roll of Dynamat! It's just a roll of the aluminum backing. Prob my fault for not catching that, but I was disappointed when it arrived.



Pretty good stuff

Written by: MJP from CT on August 22, 2013

Crutchfield Customer Review (What's this?)

Has a thin foil backing, but a good adhesive for holding the dynamat together. I probably could have gotten away with using plain old duct tape as the tape didn't seem to have any soundproofing capabilities, but I wasn't let down by the product I received.

Pros: Decent adhesive backing Thin and versatile

Cons: A little pricy for a roll of tape

Works great, easy to stick but tears easily

Written by: Wayne in Houston from Houston, TX on May 22, 2013

Crutchfield Customer Review (What's this?)

Not much to say when reviewing tape other than what was said in the subject. Seals up joints between Dynamat panels and covers lots of "sins". Worth getting.

Pros: Easy to apply, very sticky, easily follows contours

Cons: Tears easily

Completes the Dynamat install

Written by: Michael from NJ- 1995 Acura Integra on August 13, 2010

Crutchfield Customer Review (What's this?)

After applying dynamat to the trunk, rear panels and side doors; this tape came in very useful for small areas where I just couldn't use th dynamat - like the door lock mechanism, and the tail-light wires. This tape is very strong and matches the dynamat perfectly. One thing I would suggest is to wear gloves while installing since the aluminum tape is very sharp and will cut you very easily.

Why did you buy this?

Quality is good [ JAMES  Jan 29, 2016 ]

1 question already asked

No, Dyna tape alone will not do the job. However dynamat sheets like a trunk kit or bulk pack will eliminate the rattle. I've done this to a couple of rigs now it's awesome. The tape is good for taping wires down and filling in gaps in the dynamat. [ JACOB  Mar 08, 2014 ]
If by riddling you mean rattling, then no. It is a very thin tape, and if you want soundproofing capabilities you'll have to go with the dynamat itself (I think they have trunk kits but I may be mistaken). Yes it is considerably more expensive, but the tape by itself will offer zero sound dampening and you wouldn't notice a difference. [ MATTHEW  Dec 28, 2013 ]
I don't understand your question. What do you mean by "riddling"? [ WALTER  Dec 28, 2013 ]
In my novice opinion it will stop a loose rattling part if you know what specifically is rattling and can tape it down. [ KENNETH  Dec 28, 2013 ]
Andrew, I take it you mean 'rattling'. The Dynatape is used to cover exposed edges of Dynamat. It is the Dynamat that stops rattling, not Dynatape. [ GrumpyGoat  Dec 27, 2013 ]
I'm assuming you are referring to some sort of rattle or vibration related noise with bass notes in the trunk? If so this is a tape used primarily to fill the gaps or spaces inbetween sheets of Dynomat when trying to trim and finish. This tape is just the aluminum layer of Dynomat with adhesive .. It will not deaden or inactivate surface resonance. Hope this helps.... [ Susan  Dec 27, 2013 ]
Probably not. It worked for my license plate and some of my moldings, but for the trunk I had to glue some actual padding. The dynatape is pretty much aluminum foil tape. [ NICK  Dec 27, 2013 ]
No [ SHON D  Dec 27, 2013 ]
No. This tape is effectively the same as metal duct tape that you can but at the hardware store to seal HVAC ducts. It has no mat material and is only meant as a cosmetic transition between dynamic seams. [ Aaron  Dec 27, 2013 ]
