Finishing: Walls and Windows

The goals for finishing walls and windows were:  1) to cover all metal surfaces with the liner to improve insulation, eliminate possible condensation and that "cold touch" felling in winter 2) to achieve as much as possible the professional look with smooth transitions all around without any  visible fasteners.

Selecting a proper liner took some time. I tried several: couple of vinyl liners and several fabric car liners from Joan Fabric and some online stores where I could get the samples before buying. None of those tried was good for me mostly because of being too thin and not covering well the wall imperfections, or difficult to bend or not being able to make sims not so visible (abundance of rounded metal surfaces around the windows made it impossible to glue one piece of liner without sims).

Eventually, I decided to use a thin carpet, following advise of keeponvaning. I found acceptable color in Home depot: Foss Ribbed Taupe 6 ft. x 8 ft. Indoor/Outdoor Area Rug for $19.81.

 

This is the thinnest carpet I could find, and it is slightly stretchable to work on some rounded surfaces. Main benefits: hides very well the underlying surface imperfections and transitions from van body elements to plywood; makes sims almost unnoticeable. Unfortunately, one rug was just a little bit  not enough to cover everything and I had to buy the second, of which very little was used. 

Before applying the liner, significant work was needed to streamline various visible van structural elements and create smooth transitions around windows. This was done with the remaining pieces of rigid foam that was used for insulation. It was cut to size, roughly trimmed, glued with Sikaflex, voids filled with compound and finally sanded to make smooth surface and transitions.

Images below show examples of this work.

 The next step was to glue the liner. For the rear wheels boxes I used used the same vinyl cover as for the ceiling and bathroom.

All other surfaces (except in the kitchen) were covered with the carpet liner. Applying carpet to the straight walls was simple. However, gluing it around the windows happened to be quite time consuming: first take measurement of the complicated form, cut it carefully, apply the glue and the carpet piece, make cuts on the round parts where carpet does not stretch and the fill  the cuts with small pieces of carpet cut to the place:

For the kitchen area having carpet was not practical. We chose Peel and Stick Stainless Steel Tiles from Amazon ($29 for 5 sheets). It was quite a task to size, cut and apply this tile to all transitions and round surfaces around the window. I managed to cut theses small pieces of tile with the tiny Dremel cutting disc.
