Just yesterday we completed the install of most of the interior plastic panels on my J. I'm here to tell you guys that whatever they charge, pay it! That is one heck of a lot or work to do. I'm sure if I did another one it would be a bit faster but this first one was a bear. Having received the wrong panels on 4 separate occasions from Plane Plastics added a whole new level of frustration that should never have happened. IF anyone here decides to do there own interior I would highly suggest you send your panels in to have them correctly duplicated and shipped the first time. I sent detailed photos after the first mix up and still received incorrect parts.
My seats were in pretty good shape so they just received a very thorough cleaning and leather conditioning and were re installed as is. Carpet is in pretty good shape as well. We replaced all the plastic panels from the rear seat forward. The luggage area panels were removed, cleaned, prepped and SEM painted to match the new plastic we installed. The color match was very accurate so you would be hard pressed to tell the difference. First batch of paint I had put into rattle cans thinking the rough texture of the plastic would hide any imperfections of using the cans. WRONG! If you custom match and want to paint your panels, do yourself a favor and get a good adjustable compressor and paint gun system. Significant difference in finish quality when I finally used the correct tools. YMMV on this point if you are an experienced rattle can painter.
I also learned the value of using a heat gun judiciously to soften the plastic for a cleaner, tighter fit on panel joints and obstacles underneath the plastic that were not molded into the plastic originally. The visor attach points come to mind. Once I had a few screws in place to put a good tension on the panel over the attach points, I heated the panels just enough for them to smoothly mold around the fittings and then drilled holes after they cooled to run the bolt thru.
Hands down the most labor was on the overhead center panel. Cutting and aligning the multiple holes and openings was a very slow process. We then used the heat gun on several different items to make it all fit smoothly. We probably put this one piece in and put of the plane 25 times during the fitting and cutting process. Very time consuming.
A cordless Dremel is my new favorite tool for this type of work. My wife had given me one some months ago and I kind of laughed when I saw it. Sat unused in my tool box until this job. Best tool I could have asked for. Thank you to my wife for that.
End results are pretty good. I'm sure a professional shop could have done better but would have cost quite a bit. My panels were about $1,700 total. We worked somewhere between an estimated 75-100 hours on the interior alone. Again, being a novice makes this much slower.
