I wouldn't spray bed liner on top of anything other than a prepped metal surface. No matter what you do the dynamat will hold some amount of moisture and over time some part of that sandwich will start to break down.
Nice work reviving a zombie thread. I always wonder what some of the lost old timers are up to these days.

Thanks and thanks.

I was thinking along the lines of 'the weakest link' and all.

Likely will Line-X the floor, Duramat everything else and then LizardSkin the undercarriage. It's amazing how much louder my '98 is than my '67!

Few pics of Dynamat and Linex from one of our builds right now. One of the biggest sound dampeners that most forget is the bonnet and wings. Dynamat is great, but need to be prepped and primed just like any other product. You cannot apply to raw metal or it will peel. Good luck

Brian did you apply the Linex over the Dynamat? Any special prep on the Dynamat if you did?

We scuffed and etch primed it before we took it to get sprayed.

The Dynamat?

I wanted to LineX over Dunamat but have only heard terrible things. What's is your take?

I LineX's the interior then used LSI matting the interior (seat box, tunnel, etc) and the combo of the two is remarkable. Worlds of difference in both heat and noise. While I may get a little water from time to time between the layers, it seems to dry reasonable well and not retain it for long periods.

Between the layers?!? That's no good.

To piggy back on this thread: is there a stick on Line-X product out there? I would love to cover up the interior foot panels on my galvanized bulkhead to match the floor panels and tunnel covers that I recently had Line-X'd.

I have personally done it a few times, and if done properly it comes out great. If not done properly you have a mess on your hands. Linex is the only tricky spray on liner bc of the temp that it is spread at. If you is knock off Dynamat and then spray with Linex you will have a mess on your hands bc the chemical make up is different. The knock offs us a petroleum product that reacts to heat and melts, Dynamat doesn't react the same way to heat. It will get pliable but will not melt. Like paint work it is all in the prep and a good product.

Linex does very little to combat heat or sound. In fact, our entire interior of D90 is done with linex. We are currently looking into the moulded matting from exmoor to solve the unbearable heat!

Try this stuff.... http://www.lobucrod.com/

I've been using it in my 110, along with peel-n-seal... Does wonders.

at a weight of less than an oz per square foot, i am curious to know how effective it is at reducing noise.

It's not so much for noise, but heat. As mentioned that, plus the peel-n-seal/dynamat; then I covered it all with stall mat cut to fit everywhere. 3/4" stall mat does the most and it was around $30 for a 4' x 6' size.

You can hold a conversation at 80mph if the aerodynamics of a house doesn't interfere.
