Rust from refer unit

I soon found that the reason the gauges weren’t working is that there is a membrane that has to be pierced by the manufacturer.  Maybe they got into a hurry?  But then I noticed that the drip pan for the refer unit was hanging from the frame by its retaining bolts.  That was then I knew there was no quality control.  The typical US auto maker syndrome of not turning bolts was already apparent.  No biggie I thought.  My next issue though cropped up not long after powering on the refer unit.  I kept hearing this cracking noise.  It was coming from the refer unit itself.  When I removed a panel I noticed that the sheet metal shell which someone wrapped to hold the spray can variety PU foam insulation was being held (in part) by duct tape (one seam is shown below).  This duct tape was splitting due to the temperature change.  The next problem I noticed was all the water collecting on the drain plate (inside the refer unit).  This caused extensive rusting of the frame (a portion is shown above as well for your amusement).  Then came the real surprise.
