Some suggestions if you plan to remove the interior and install Dynamat, speakers, wiring, switches, or anything else.

1. Take pictures of everything before disassembly. If you don’t take enough pictures during disassembly, you’ll see which ones you should have taken when you try to put everything back together. You can take them before the next disassembly.
2. Have boxes and zip lock bags available.
3. Get a couple of sets of plastic panel removal tools. This will prevent damage and make the job easier. I have two sets of four tools, but I seldom have all eight at one time.
4. Get another Fit to see how things should go back together. My son’s Fit came in handy a couple of times.
5. It will be easier leaving the thick rubber weather seal in place as much as possible. I removed some and left some. Removing only what you need makes it much easier to put it back on.
6. There are lots of sharp edges, so be careful, and have Band Aids handy. Blood can stain. The clear plastic liner on the doors is held in place with an incredibly sticky, gooey black adhesive. It will get on your hands and everything your hands touch. Alcohol is a good remedy. Just don’t drink too much, or you might mess up the job. Rubbing alcohol works well for removing that goo from your hands, but it will really, really hurt when it gets into all those little cuts you got from the sharp edges.
7. Put all fasteners into zip locks and label them with a marker.
8. Put larger plastic pieces into boxes.
9. When you remove plastic body panels, label them on the inside. You can use stick-on computer labels or paper and Scotch tape. You can also go out and buy a nice label maker and use that. These pieces look very similar after they’ve been off the car for a while.
10. When you remove panels, those green clips may stay in the body of the car. Remove them immediately and put them back into the panel.
11. It can be very difficult to get the door panels back on. The door handle is loose to float around, and it must line up with the opening in the door panel and the hole and threads in the door to attach it with a single screw. It can go on quickly, or it can be a nuisance.
12. Save all the leftover bits. You might find where they belong during your next disassembly.
13. Save the vacuuming till after the work is done, although vacuum under the seats, if you remove them.
