Pretty much. Did this yesterday:



The heat gun took much of the material off in a fairly routine fashion. Almost all of it came off easily, but the stuff on the floor between the trunk and rear seats is awful, still working on that.
You can see on the trans tunnel that regular paint thinner removed the leftover adhesive. Which is great, I expected that job to be much more difficult. The only problem is it really gunks up the scrub pads and rags that I'm using.

Lots of time going into this task. My Dad came over and cut off a bunch of unneeded brackets, so that was a big help.
