about 5 years ago someone on the old board posted a good dynamat alternative available from mcmaster carr...it had a sticky back, flexible feel to it and worked really well..i ended up buying about 75 square feet of it.. 6 sheets for about 12 bucks a sheet i believe....


anyone have a good alternative to dynamat or even has used a product similar to the one i posted above?

thanks in advance

I used to be part of one of them car audio forums back in the day and they used to rave about Rammat...don't know what the guy's name was but you can do a search for Rammat on E-Bay and come up with results for him if he's still around...i apologize if he's not in business no more but the stuff comes in like 100' rolls and is pretty cheap compared to dynamat. Hope he's still around.

i was just on mcmaster carr's website and in their find box if you type 3274 and scroll down to their Adhesive-Back Damping Sheets section, i think i purchased part number 9709T19

it seems like thats what i got,...but i remember it being a little bit thicker...could be my old age....



afcajun....thanks for the info....

Hey Yunny!

Generic Dynamat Original from McMaster is the polymeric mastic (formerly known as hi-temp mastic) (part# 9709T19, page 3274)

Generic Dynamat Xtreme from McMaster is the 3-ply aluminized adhesive-backed damping sheets (part# 9709T25, page 3274)

NOTE: I've only used the hi-temp mastic, and I know for a fact it's truly generic Dynamat Original. I have been told by several people that the second item listed is the generic Dynamat Xtreme, but I've never used it, so take that for what it's worth. But looking at the specs for the Dynamat Xtreme and McMaster's material, they do look to be identical.

Did you get rid of your carpet in the process, or did you re-install the carpet over the line-x?

How much did you spray up the sides? Was it just the floor? How far up the sides? All the way? Thanks for the info, sounds like a great price for Line-X.

If I remember correctly (it's been several years), I ordered around 100 sq.ft. and used around 80 of it. I had a couple sheets left over. I put several layers in some places, so you could end up using maybe closer to 50 or 60 if you're just putting a layer or two in most places.

In my old truck I sprayed the interior with Plasti dip under the carpet...I won a under 200 watt class stereo contest back in the day before it became a serious contest like it is these days...with a crappy toyota pick up interior no less

took next to no prep and did a great job cutting down noise...I lined my sub box inside with it as well!
newspaper and most any closed cell poly foam absorb unwanted sounds well!!
Dupont Tyvek material works well to...if you pick up scraps at a construction site ...or off a trailer* wink wink hehe j/k

I posted about asphalt paper a while ago as well!

If you are in Houston drop me a line, I have several sheets of the High Temp Mastic you can have. I think shipping was as much as the sheets.
