dynamat tape

Written By eric, lemoore, ca on Thursday, April 10, 2014
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.
thin aluminum, very adaptable/formable.
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.
Custom look
30 feet isn't very long.

Not quite what i expected.

Written By Thought it was just like Dynomat..in fact it is ju, Warren, CT on Thursday, 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.
Nice Dynomat Lettering on outside
Same stuff at the hardware store only for less, less the Dynomat lettering

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, CT on Thursday, 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.
Decent adhesive backing Thin and versatile
A little pricy for a roll of tape

Works great, easy to stick but tears easily

Written By Wayne in Houston, Houston, TX on Wednesday, 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.
Easy to apply, very sticky, easily follows contours
Tears easily

Completes the Dynamat install

Written By Michael, NJ- 1995 Acura Integra on Friday, 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.

Would this stop my trunk from riddling? [ Andrew  Dec 27, 2013 ]

  • 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. [ GONDOLA   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 ]
