I'm a mechanical engineer in a computer science world, and damping resonance is my outlet
Yeah, I figured Florida might require the butyl rubber solution.
- It's a lot easier to get into the fenders if the front is lifted, yes. You can do this with a jackstand on each wheel though, no need for a lift or anything.
- It's thick foam with a mass-loading vinyl (MLV) layer over it, not something like Weathertech. Second Skin's previous product had foam attached to the vinyl sheet and that's what I have now; as that's gotten expensive they sell both separately.
If I had to do it again I would get a layer of Overkill Pro (thick neoprene foam) and use some 3M adhesive to stick Luxury Liner Pro on it:

My third row is never up unless I'm cleaning the leather, so I have a sheet like this from the back of the second row all the way to the tail gate.
I'm happy with the heavy foam/vinyl sheet I have since I'm putting dirty mountain bikes down on it all the time, but if you wanted something nicer a Weathertech tray would probably sit right on top of it with no issues.
