Energy Consumption

One interesting thing about the Volkswagen is how it can display the top three energy consumers in the car.  As I played with internal settings, I found some surprises.

In this first shot, I have the driver's seat set to maximum heat, the wing mirror defrosters on, and the heat set at 72 degrees.  It was a balmy 15 degrees fahrenheit, and the coolant and oil were at operating temperatures.


What surprised me was what happened when I fired up the rear defroster.  It consumed more energy than the seat heater - I didn't expect that.  In my small sample size straw polls, most folks think that a seat heater would consume more electricity than the rear defroster.



Predictably, when I maxed out the passenger's seat heater, it dropped the wing mirror power consumption out of the top three.



Turning of the passenger's seat heater and dialing the driver's seat back to the middle of its three settings brings its energy consumption down to parity with the wing mirrors,



while using the lowest of the three settings on the driver's seat consume even less power than the wing mirrors.



Again, it's just a neat detail that car people might appreciate and find interesting.  I suppose this would be another thing to add to the "delighters" section of this post.

Taking Care of Business

I noticed that the grey van had a bit of a rust bubble on the driver's rear quarter panel, near the top of the wheel arch.  With the rust spot in a relatively inconspicuous place, and the van at the ripe old age of 12, I decided to take on the repair myself.

Let it be known that I have zero experience with bodywork.  That said, I do have a Dremel and willingness to experiment, so I decided to go for it.

The first step was to get rid of that cancerous rust.  I put on some safety glasses, selected a cutting tool, and went after it.  From the side, I didn't have to grind away too much of the paint and rust:


However, as you can see in the next picture, I did slip and ground away some perfectly good paint.  Not my intent, and I certainly muttered under my breath when that happened.


If you lie on the ground and look up at the fender, you can see where the metal folded in and where the real problem was:



I popped out to AutoZone to pick up some supplies, including grey metal primer, masking tape, a small can of Bondo, and some very fined finishing sandpaper: 


When I got home, I took a closer look at the fender, and saw more rust lurking:


Back to work with the Dremel, I cut away more and more rusty metal:



Looking around, I still wasn't satisfied that I had eliminated all of the rust, so I ended up with a pretty decent-sized hole that I cut away:



With all of the surface prep done, I plied my Bondo skills for the first time.  Again, since this was in a hard-to-see place, I wasn't concerned with perfection - I just wanted to eliminate any rust spread.  My first attempt was kind of lumpy:


I worked it a bit more, smoothed out the Bondo, and taped off the area for priming.  I also covered the wheel and tire to catch any overspray:

I have past experience with spray paint, so I slowly and methodically added layer after layer:

Hot halogen work lights helped accelerate the drying process:

My end result certainly isn't perfect by any stretch of the imagination.  I could have spent much more time wet sanding to get closer to a nice, even finish.


However, my goal was "good enough," so I applied a top coat using the touch-up paint I keep for rock chips and called it a day:

A bit later on, I noticed a bit of rust starting behind the fuel filler door.  I think this is a design flaw on Honda's part, as there is no drain hole.  When it rains and you pop the filler door open, you can see where the water accumulates.

Once again, I decided to get out in front of the rust before it became a problem.  I attached the rust spot vigorously:


Once again, my repair was crude but functional.  The van still looks good from 20 feet away or so.

Another thing I've noticed is that as the van has aged, the headlights have become somewhat foggy and cloudy in appearance:



I got pretty aggressive with a polishing compound, and I was pretty pleased at the result.  Again, not perfect, but much of the cloudiness had been polished away.


If you take care of your equipment, odds are it will take care of you.  This is one of the reasons I enjoy hand-waxing and hand-washing the vehicles.  It gives me a chance to really scrutinize the body and see if there are any potential issues out there, lurking below the surface.  Rock chips on the nose?  Just take care of them.  Take an extra-long look after winter or a long road trip, particularly around where the hood meets the front fascia, as stone chips there are harder to see.

With over 177,000 miles now, the grey van is halfway to 300,000.  With a bit of care and attention, I'm doing my part to ensure it gets there.
