Ok, we’re getting closer.  I spent some time with the needle scaler today and got the rest of the undercoating (among other things) off the bottom of the luggage shelf.  It’s starting to look nice and clean under there.   🙂  The other day I pulled some plastic shielding and really thin aluminum wrap off of the heater tubes (you can see them installed in the pictures of my previous post).  I took a picture of them today.  I’m thinking these were original to the car, but I don’t think they can be purchased anymore (I may be wrong though).  It seems most people take then off anyway.    Mine were very brittle, damaged, and pretty much crumbled in my hand.  I removed them too.  I’m guessing they were used for insulation?
