Our '83 westy has very little seam rust as seen from the outside, but my
understanding is that the rust is probably mostly hanging out in the
interior of the seams.  I'll probably do the whole POR15 routine on the
exterior of the seams.  As for as the other side, I've been thinking
about taking out the interior, inspecting the inside metal, grinding
down any rust, and then spraying it with some coating (Boeshield?
Penzoils Marine Rust inhibitor?) and putting everything back together.

A couple of questions...
are there detailed instructions anywhere about the best sequence to
remove the westy interior in?  Right now my fridge works very reliably.
I'm worried I'm likely to put everything back together wrong and find
out I've messed it up somehow.

any ideas about what to replace insulation with?
While I have my fridge out, should I stand it upside down, shake it,
jump on it, or anything else?
Also, how long should doing the interior take?? I don't have a garage in
which to store the cabinets/fridge/etc while I'm doing the job.  So if I
could do the whole inside in one day that would really make me more
excited about the operation.

Thanks very much for any suggestions.
