Door Vapor Barrier
Since doing the repair on the left (Beetle door), I have found that Tyvek(R) house wrap makes great vapor barrier replacement (as seen above). I even taped it with the Tyvek(R) brand construction tape. The house wrap/tape procedure is faster and simpler, and probably better lasting than this procedure. The only hitch is that house wrap is only sold in huge rolls.
This procedure uses vinyl sheet that I bought at a fabric store.
