What's up with Forester?

After all those Impreza Rust Diaries, it’s finally Forester’s turn for some love. This week, it’s time for an oil change, and since the mileage is steadily increasing, the spark plugs were also due for replacement, as per the book.

For the record, at 305969km:

Rust Diaries: Post scriptum

Since Tomek is currently laying down the carpet in the Impreza and will soon start installing the seats, I thought it would be a good time to write a little summary.

Is it worth it?

Yes, definitely yes. Time takes its toll, and although this particular example was in objectively good condition (see sills, shock absorber mounts, and fenders), I don’t know how it would have looked in a few years time. Now, I can sleep a bit more peacefully. Besides, there’s a lot of fun in all this work — we laughed like beavers chomping on aspen twigs. There’s also satisfaction — maybe not exactly “build not bought”, but something along those lines.

Rust Diaries: The interior

During the summer holidays, we stripped the interior from the dashboard to the trunk; now it’s time to finish the job. Although I’m already in Poznań, Tomek is still working on it. The condition is actually very good, no holes or deep rust pitting.

The method is exactly the same as for the undercarriage: stripping, sanding, and using the chemicals. The only difference is that instead of Cobra, Tomek is applying 02C paint as the final layer.

Rust Diaries: All things are important, but some are more important

Of the important ones, with a big smile on my face, I’m happy to report that the Impreza will soon have all its clips in perfect condition. I spent a fair bit of time under the car and noted all the missing, broken, and suspiciously hanging by a thread clips, and as always, my local Subaru specialists stepped up to the task. I’m also really happy about the sponges for the fuel tank roll over valve and fuel pump access flap, they were in pretty bad shape, and are notoriously hard to come by.

Rust Diaries: The chemicals

Since I’m not a painter and don’t really have anyone to consult on the matter, the only thing left for me to do was to go through a huge number of threads where car enthusiasts battle with the oxidation of iron and its alloys. The real results are delayed, so my choices will be verified in a few years — who knows, maybe I’ll have to eat my words. Here are my conclusions, in the order of application (for the visually inclined, photos follow).
