[A/S] lining a '79 bath shower

Hi Christopher,

The photo gallery is on the Vintage Airstream page:  
<http://www.tompatterson.com/gallery/albums.php>  Ours is "Beer Can 
One".

In a nutshell:
  I firred out the walls with 1/8" luan underlayment first. The original 
shower corners were (and still are) aluminum extrusions that do a good 
job holding the walls together- but they stick in to the room a bit, 
and so the luan gave me just enough depth to create a smooth surface; 
it also allowed the vinyl liner to lap over the shower pan smoothly. I 
glued and screwed the Luan to the 2 walls. I took my time, made paper 
templates, and got the luan to fit very well. Once I was satisfied with 
the fit- and before I installed the luan- I used it as templates for 
the vinyl. I cut the luan with a jig saw and the vinyl with a sharp 
razor knife.
I also made a plywood wedge to transition over the ductwork running 
along the back of the shower, so as to eliminate the shelf the duct 
created. This became a bit of a chore, as I wanted the wedge to have a 
mild "S" curve, blending nicely with the curve of the outside wall.
I chose to use a white vinyl material, about 1/16" thick, sold at a big 
box for just such wet applications. There are flexible plastic moldings 
available to do inside corners. I backed these up with caulk just for a 
belt to wear with my suspenders. The vinyl is held to the luan with 
special adhesive and plastic rivets that are designed for this 
application. These aren't pop rivets; you drill a hole, stick the rivet 
shank into the hole, and drive a plastic nail in with a hammer. The 
nail causes the shank to expand and hold tightly.
I was able to get the edge of the vinyl to fit neatly into the aluminum 
roof panel seam, and the wall adjacent to the door (directly to the 
left of the sink) to fit in to the aluminum extrusion that forms the 
door jamb. Took a bit of persuasion, but results in a nice clean line. 
Shower head and mixer valve penetrations were cut to fit tightly and 
caulked.
All in all it was a fairly big job, but we're happy with the results 
and feel the effort was worth it.
Let me know if you have more questions or need more photos.
