Hello all, I’m in the process of installing a custom kit form Flatline Barrier specific for my 1968 corvette. I started in the rear cargo area and laid out based on the installation diagram...when I lay out the pieces (dry fit) there is all sort of non-covered area (perhaps 8"~) all around the pieces. Not sure if this is the way it was designed to fit? Was hoping someone out there had some experience w/ this product.
Thank you
Yes I purchased a kit just like that one from Zip Corvette products when I was sound deadening my car about 2 years ago. Being overseas it cost me plenty. What with the exchange rate and cost of overseas shipping. And Zip didn't have it in stock when I ordered so I had to wait almost 2 months before they got it, and then finally shipped it to me.
I found this Flatline Barrier pre-cut kit to be a complete and total waste of money! Just awful! And absolutely no instructions whatsoever. I complained to Zip LOUDLY. They finally put me in touch with the Flatline barrier company. Who didn't return emails!
In the end, I purchased sound deadener locally. Was MUCH denser and higher quality and lower cost. But I had to cut it out myself. But having that many gaps under the carpet just simply can not work! Or look good under the carpet!
I put in a negative review on Zip Corvette's site. They promptly removed my negative review. I thought that was bullshit! In the end Zip refunded some of my Money.
Sorry to hear you purchased this kit.
On my hot rod projects I used Dyna Mat "like" insulation from Summit. Cut and paste to cover every inch of the interior floor pan. Then the double sided foil insulation with about 3/8" fiber insulation. I use the universal kits because I'm cheap. LOL.
The Dyna Mat "like" is self sticking. The 3/8" insulation I use 3M spray glue to glue it the first insulation.
Don't have a pic of my C3 but a pic of my 68 C10 before installing the carpet.
On the under side of the floor pan I use a DEI product that has glue on one side, fiberglass insulation and then some kind of a waffle SS or alum material over the header area.

Thanks, guys, for the feedback... I had also called Flatline directly... Spoke top Dan (owners son).. His response was they have made the product for years like this? and that’s it! ... Ok i guess they been doing wrong for years
Seems they really are no interested in feedback from their potential customer base… Great business model
Well in defense of this practice, GM does that also that on new cars.
Each panel on a car has a resonance frequency at which it will vibrate and you can hear it, because it gets louder than normal at that frequency.
GM adds many square tar like panels in the center of a door skin, trunk floor, etc, to dampen that resonant frequency out, and make the car quieter. That frequency is eliminated.
It is not the same as complete coverage that acts more like a a blanket that dampens or reduces the volume of all frequencies.
Both have their place.
One takes care of the majority of the noise volume at a minimal cost, and easier application.
Complete coverage can still be more effective overall. But by what percentage improvement? And at an obviously higher cost and installation labor.
My Caddy has all the above, with 2 inch thick floor carpet, with several layers. And it is very quiet. And I have measured it. It does still has some resonance at certain frequencies.
I understand what your trying to say about the OEM'S use of smaller bits of insulation or dampeners.
However, when ordering this precut kit from Flatline Barrier I believe we are expecting a full coverage type of installation. It's not like they are giving it away.
I can only say that I for one was truly disappointed.
This I find both interesting and disturbing.
I once purchased almost solely from Zip for Corvette specific needs.
I have shifted my alliance to Bairs Corvettes.
The practice of removing reviews that are less than complementary defeats the usefulness of said reviews. It's border line business practice at best.
