I purchased more materials than needed for my soundproofing project, and so I'm offering up the leftover materials. HUGE improvement over stock, much quieter, the sound system kicks, and the cabin stays cooler.

Items for sale:
-Second Skin Spectrum sound deadener coating, 1 gallon, unopened ($80 OBO)
-Noico RED 150 mil self adhering closed cell foam heat and sound isolator, 36 sq ft, unopened ($45 OBO)
-Sheet rollers, open-box unused ($10 OBO)
-Second Skin butyl tape, about half a roll left (free)

HMU if interested, will consider shipping and bundle deal

I've been thinking about diving into this myself, so out of curiosity: how far would all of these materials get you? Enough for front doors, floor, and roof? Or a subset of those?

Awesome! I'd say it depends on how crazy you want to go with the project. The audio specialists I talked to, and the videos online that I watched, pretty much agree that you get a lot of benefit from just doing key areas like the doors and front floor. After about 60% interior coverage, the returns are diminishing.

1gal of the Spectrum will do all of the side doors (front and rear) of the FJ or the entire headliner with a standard coating, or probably just the fronts if you do a double coat.

For the foam, that should be enough to do the doors and the rear pillars, possibly also the tailgate.

The tape is really useful for preventing clips from rattling, and I think that the amount I have left should be enough.

The Spectrum is sort of a liquid equivalent to the butyl rubber sheets. Pros of the liquid is that it's easier to get into tight spaces. Cons are that it's messier and you have to let it dry. This layer takes out the structural noise of the vehicle, so you hear much less exterior noise and car vibrations.
The foam goes over the rubber layer to provide insulation and noise isolation.

I ended up doing the entire cabin, and I am very happy with the results. I had all the materials so I figured why not. Much quieter, the cabin holds a temperature better, and the system sounds SO good. I did rubber on as much sheet metal as I could, plus foam on the doors/pillars, vinyl on the floor, and a flax/jute headliner. I probably could have gotten away with less for a very similar result, but I did the whole cabin because 1) my dog (a 150lb Newfoundland) rides in the trunk, and so I wanted him to enjoy a nice cool cabin as well, and 2) the interior was already out so why not.
