Just to be sure, you added the Herculiner, carpet, and then vinyl in the cargo aera? May I ask what vinyl you used on top of the Herculiner?ShagWagon wrote:I did herculiner. Scruffed up the floor with a wire brush and used acetone all over before applying two coats. Took one gallon.
Also applied on roof before my headliner and screwed roof rack right into it.
I'm happy. Covered it with carpet kit and a vinyl in the cargo area. Makes a big difference in sound deadening. I don't know who would say it doesn't. Rubber doesn't carry sound very well.
Hmm. Thank you. So for my purpose (mainly sound and heat/cold), it would be best to put a layer of foam, a layer of vinyl, and then the carpeting, yes? It is always not to be able to have an extra layer of moister protection if at all possible. If this is correct, may I ask what kind of foam to use before the MLV or heavy vinyl?SJTD wrote:It's been done but Dynamat is an expensive way to "deaden" sound. Its main purpose is to take the "bong" out of panels and full coverage isn't required for that.
To block sound most effectively you want a thin layer of foam, closed cell so it doesn't absorb water, then a layer of heavy vinyl or "MLV" . The foam is a decoupler and prevents noise being transfered to the vinyl.
Using Dynamat is not as effective as the layering because the energy is transfered directly to it from the metal.
Neither is a layer of Herculiner or Line-X.
Was from a ACC vinyl kit the PO threw in he had bought. I didn't put it on the front and rears. Left the carpet area for where the people sit. The vinyl where the dirty wet dogs, goats, car parts and lumber sits.Santeh wrote:Thanks again for the thoughts! I greatly appreciate it!
As my main reasons for thinking of lining the floors and cargo door in my 1978 Jeep Cherokee was to help with heat and sound, I was doing some more reading and I was curious if, instead of lining the interior of the jeep with something like Line X and then carpeting, I went with Dynamat and then Essex carpet on top of the flooring (please see: https://www.amazon.com/Dynamat-10455-Se ... ds=dynamat). Has anyone tried something like this?

Thanks all!
