Problem#8 - wood panels degraded

Post by AKROVER »

Image

This project is done, at least for now. It isn’t perfect, but like outside of the car, you don’t see the imperfections unless you get close. It is a 1000% improvement over the cracks that were in the clearcoat when I bought the car. What is amazing to me is that the cracks in the veneer have vanished now that the clearcoat is ultra glossy. I don’t know why that changed, but I can’t find those lines anymore.

Image

Refinishing was a painful process and really needs to be a progression of finer sandpaper and finally perhaps even a couple of steps of different polishing compounds. I initially tried wet sanding with 600 grit and then polishing with Meguiars which is a very fine finishing compound. The 600 grit scratches were too much work for the polishing compound. The next attempt (after a walk to Ace Hardware to get some different sandpaper) was to add a couple more coats of lacquer and then wet sand with 1500 grit befobefore polishing. That might not have been aggressive enough as rattle-can lacquer doesn’t lay on quite that smoothly, but the 1500 eventually took out the high spots without too much effort. The polishing compound took me from there to the finish, but not without a lot of elbow grease. I think 2400 grit paper after the 1500 might have been a better process, but the real problem is keeping the sandpaper and polishing rag clean as any dust spec can become a deep scratch. The finish is mostly perfect glassy finish, but I might not have put enough lacquer on as some of the wood grain still shows through as surface variations. That really makes it look a lot more like wood than the factory finish which really looks like plastic, but all of that only matters when inspecting this from a very close distance. Throughout the polishing, I was inspecting this under a light so I know I did a really nice job, even though I also know there are still surface imperfections.

There is a visible difference between what I refinished and what I didn’t. The old stuff almost looks a little milky. My work looks deep and rich. The only place it matters is that passenger outboard vent surround. I noticed that the wood grains are carefully matched at the factory and the lighter color matches the transition that happens on the glove box panel right near the edge. That vent surround piece is fundamentally lighter in color because the wood is, but I think there is a texture and clarity difference that makes it seem slightly mismatched. I might pull that vent surround back off and refinish it now that I have a good idea of what the process looks like, but I don’t feel like sanding and polishing in the near future.

Reassembly is always a time to put things together better. The glove box now closes more positively thanks to a better adjustment on the catch. The corner of the dashboard near the A-pillar is warped and that was pushing that outboard vent surround inward. I removed the vent surround and ground down the corner that was up against the warpage and that went together looking a little more level with a more even gap along the glovebox.

The cigarette lighter in the center console was still a problem from reassembly after the vinyl installation. There was nothing holding it down because all the plastic clips are broken. Initially, the thickness of the vinyl gave it an interference fit, but it kept popping up. There is a light in that assembly that is mounted on the cylindrical body of the lighter and the metal box that holds the light ends just far enough under the bezel that it made the perfect clip (picture below shows light box, picture is not mine but from internet). By pushing the bezel down and then rotating the internal assembly, the light box actually clips under the vinyl covered steel plate and holds it down on the gearshift side. The other side still has one plastic clip that seems to be providing some hold. The reason I am explaining all of this is that if I ever need to remove this again, I will know to rotate the cylinder within the bezel counterclockwise so that the light box is clear of the steel cutout and the entire assembly should lift out, perhaps with a little resistance on the upper right corner where that last somewhat functional clip sits.

Problem#11 - fog lights not working

Post by AKROVER »

I decided to tackle the fog lights. In preparation yesterday, I pulled out the wiring diagram for the fog lights to make sure I fully understood the circuitry and where I might be able to test it. Before going out to the garage today, I took one more look at the wiring diagram and realized something strange; the headlights work with the ignition off, but the fog lights don’t. It turns out that I never tested the fog lights with the ignition on. The driver’s side light actually works, although it seemed rather dim. When I took apart the passenger side, I was able to verify power, so the bulb is burned out. Both lenses have been damaged, and I suspect the reflectors on both sides are pretty much shot. There are rusty bits inside the passenger housing that is sitting on my desk right now and I remember the driver’s housing being a bit ugly, too, when I took it apart the first time I tried to diagnose the issue. The original assemblies were made by Hella, but getting an exact match would require spending silly amounts of money for a used and very old piece. I decided that the current aftermarket Hella’s looked similar enough and the mounting looks identical, so a set is on the way.

I also spent some time addressing the usual annoyance with classic cars, the lack of cupholders. In the old days, you could walk into any cheap store and find something, but I couldn’t find anything that would really work in this car. A few weeks back, I bought a couple cheap cupholders off Ace Hardware’s clearance shelf and today I built a wooden base that fits between the back seat and the center console and straddles the transmission tunnel. I covered the wood in the same vinyl I used on the center console, although that really doesn’t make too much difference since it isn’t particularly visible. It gives us two cupholders in a somewhat awkward place, but it is better than nothing. In this dry climate with lots of long cruises in the hills, it is often necessary to take some water with us.

It is a shame that my design blocks the backseat passenger's ashtray.

When I'm sitting back there and want to smoke, I'll bring my own cup holder smokeless ashtray.

Problem#11 - fog lights not working

Another problem resolved. Installation was pretty easy. I replaced one connector on each side but was able to reuse the existing wiring. The brackets were very similar, but I used the new ones as they were cupped for the plastic housing. The old housings were metal with a chrome finish and these are black, but no one will notice that underneath the car. The old lights were a little more rounded in shape, but almost identical in size. The new lights came with plastic covers that I doubt I will ever use, but the white plastic with the black Hella logo is retro in its own way. This is just the cheap set, so everything is plastic. I started the car for the first time in a while. It fired up right away and it backed out of the garage normally.

Your fog lights look great. When are you getting a
Leaper?

Thanks for sending me down that rabbit hole. I wasted an hour or so reading about hood ornaments on Jaguars which is a surprisingly divisive issue. Jaguar never put a leaper on the XJ-S. Many dealers did. One cosmetic issue with that is the slope of the hood; the leaper leaps downward. Most XJ-S’s came with a badge on the hood, aka the growler. The growler badge was either black or gold. The gold one on my car was part of the ‘Classic Collection’ package available ’88-’91. I think later cars were only available with a gold badge (different hood and different badge) and prior to ‘88, the only badge was black. I think prior to ’82, there was no factory hood ornament at all. There was an aftermarket leaper produced for awhile that used the same mounting holes as the growler badge and had a circular base of the same size which would cover any paint issues. Apparently, that leaper was leveled off for the slope of the XJ-S hood. Those don’t appear to be readily available anymore. Nice leapers can cost hundreds of dollars, although aftermarket ones can be very cheap. They are also sometimes stolen, often ripped off with brutal consequences to the hood. Since I really like the gold badge on my green hood, and since I already owned a car with a leaper, the short answer is NEVER!

I’m still a huge leaper fan, BUT I’m also someone who likes the
stock look the most. I guess Jag didn’t see it fit to put the Leaper
on, so you’re stuck with a badge. On to the next problem for you.

A week and a half ago, we hit negative 20. We had highs in the 60s for most of the last week, but that slab in the garage was still pretty cold and the moisture dragged in by the VW had the humidity in the garage very high. It has been damp and cold out there, but today I finally opened a garage door and turned on the heater. It quickly felt much better.

My project for today was to put in a dead pedal. My left foot did not reach anything so it just rested there like it would sitting in a recliner. That free-floating left foot made me feel completely unbraced when driving through the curves. I had been out in the garage a few times in the last couple of weeks thinking about this project, so I had already identified an available mounting point on the firewall. As I experimented with various bracketry, I landed on a rather simple approach. I bolted a short piece of flat stock to that mounting point, bent it at an appropriate angle, and mounted a chunk of 2X4 to it. The flex in the flat stock does allow the 2X4 to press firmly against the floor, but it also allows flexes the other way for keeping the carpet clean. I don’t really have carpeting in the front footwells, merely original Jaguar floor mats. After installing my dead pedal, I realized the driver’s floor mat would sit over the top of that 2X4 without risk of interfering with the brake pedal. Cosmetically, that looks better than a chunk of lumber in the footwell, but perhaps I will cover that 2X4 with something visually appealing and put the floor mat back underneath. For now, though, I have made a huge improvement for driving. It is a relatively relaxed position for the dead pedal, a fuller extension of my leg than in the VW, but I am now making solid contact with the car. Obviously, I took the car out for a 25-mile drive to test it out. The car fired right up and drove great, but I did have to air up the driver’s rear tire as it was down to 20psi.

There is a slight puddle on the garage floor under the car, but it is pretty insignificant. I think the power steering rack leaks when it sits, but I am not 100% sure it is power steering fluid. All the fluid levels were fine, but this puddle really doesn't amount to much. Old cars are leakers, Jaguars probably more than others, but I expected worse. I consider this good news.

Every little sub project makes the ol' Jag that much better and more satisfying to own.
