I was going to suggest Evaporust, great stuff if you have time to let parts sit.

I've been on vacation for a little over a week and never got around to updating what was done before i left...
The bearing caps were painted, as may have been seen in the beckground in earlier pictures.
Image

Then I started disassembling the rear brakes...
Image
Image
Image

I also ground in the new brake shoes to match the drum. These had maybe 10% contact when I started sanding... Dust mask on!!
Image
Image
Image

And just like that, one side was assembled!
Image
Image
Image

I also replaced both parking brake cables
Image

With the bearing cap in place and new seals installed, it was just a matter of fitting the drum, which had gotten a thin layer of black high-temp paint.
Image
Image

With that done, it was time to move on to the front brakes.
Image

The drum was quite a sorry sight, to say the least... But cleanable!
Image
Image
Image

Someone has definitely been here before and replaced the wheel bearings at some point...
Image
Image

After a soak, some sanding, and a bit of paint, that drum turned out nice too.
Image
Image
Image

Once again I sanded the shoes to fit the drum. Here you can see how little contact area there is even after some sanding.
Image
Image

As you can see, the brake shoe is thicker in the middle after sanding. This is something I haven’t tried before… But it kind of feels like it should give better braking power right from the start. Even though the shoes will wear in over time.
Image

With the drum painted and warm after lying in the sun, there was no issue getting the new bearing races in.
Image

Plenty of SKF wheel bearing grease was used to fill the cavity in the drum and pack the bearings.
Image
Image
Image

The brakes were assembled and installed on the car
Image
Image
Image

I had bought these EMPI aluminum locknuts with hex screws to avoid those slightly annoying double nuts. But the aluminum locknuts are huge! And I don't think the center caps for my BRMs will fit over the grease cap. Whether I should cut down and reweld the grease caps, or just bash them in with a hammer, I'll end up going back to double nuts... Right now, it's temporarily tightened since I haven't mounted any locking plates.
Image

Next time I'm in the garage, I'll bring a wheel and test it out! Should be exciting…
Until then!

The front wheel's center cap fit perfectly over the grease cap. However, it looks like it's taken a bit of a beating earlier in its life.
Image
Image
Image

It fits in the back without any problems too.
Image

I read a bit on the forums about the Flat4 BRM wheels, and apparently the speedometer cable is also supposed to fit inside the center cap if you grind down the grease cap where it bottoms out in the drum. So I ground it down about 3–4 mm and also ground down the end of the speedo cable.
Image

The brakes are mounted on the driver’s side too.
Image
Image
Image

The cable just barely fit!
Image
Image

Had to snap a little inspiration photo with the fender on!
Image

The transmission has also been filled with fluid as well.
Image

Next step was a bit of plumbing. All brake lines and hoses will be replaced, as well as the master cylinder.
Image
Image
Image

The old brake fluid reservoir came out too.
Image

Old and new! Upgrading to a dual-circuit master cylinder.
Image

First, a bit of paint.
Image
Image

Assembled
Image

I reused the original boot for the pedal since it had a better fit and was surprisingly fresh.
Image

Installed in the car and brake lines made.
Image
Image
Image

New lines in the back too, of course.
Image
Image
Image

Before the pedal assembly was mounted, I cleaned the rubber section of the mat behind it.
Image
Image
Image

Then it was just a matter of filling the system and bleeding it. Thanks to Roger (Local Twin Peak Boxers-member) who helped me with this!
Image

Now she’s out! Rolling and braking!
Image
Image
Image

We did discover, however, that one side in the front needs to be adjusted for correct camber… I’ll need to move a few shims in the spindle to correct this.
Image

This also means everything has been filmed for Episode 2. Coming soon! Next step is to get some paint on the repaired areas and fenders.

These past months work can now be seen in video format on Youtube.. This episode turned out to be longer than expected...

Well, some work has been done!

First off, I re-shimmed one of the spindles
Image
Image

Brushed some black paint on the floor pan. Better than nothing and there will be a carpet on top of this anyway..
Image
Image

Then it was time for some paint! So I brought the fenders into the other room and sanded them down to bare metal on the top side. The underside I’ll just paint the repairs quickly and smear with undercoating.
Image
Image
Image
Image
Image
Image
Image
Image
Image

With the fenders clean, a wash primer was applied.
Image
Image

Then the filler went on like crazy. Warning for sensitive viewers. Especially anyone out there who works as an automotive painter..
This paint job turned out really quick n’ dirty with a lot of filler..
Image
Image
Image
Image

After about 3 rounds of filler and sanding, another layer of wash primer was applied to protect all the bare metal areas before high build primer.
Image
Image

A few solid coats of primer was applied and sanded down to the finish my non-sanding primer required.
Image
Image
Image
Image
Image
Image
Image

Why do I even have a non-sanding primer i hear you ask? When I ordered the paint, the can said it required a white primer. I did a couple of test pieces to see how the color would match. One with white primer and one with light gray.
I polished a section on the front hood and on the engine lid to test the color in both shade and direct sunlight.
Image
Image
Image
Image

One of the samples turned out slightly darker
Image

And the other one a bit lighter
Image

Confirmed that a white non-sanding primer should be used, so all the fenders were painted after the sanded-through areas with bare metal spots were covered with more wash primer..
Image
Image
Image
Image

All set for the topcoat!
Image
Image
Image

Some dry spray in a few spots and a couple of nasty runs on one rear fender.. The paint needs to cure properly before I start wet sanding and fixing the flaws.
Image
Image

The fenders are far from perfect with a few minor dents left and some waviness where I used filler. But the car they’re going on isn’t much better, so this will do just fine for me! This is not the right way to do it and I’m definitely not a car painter..
Now the car has been moved into the hall and is propped up and masked off, ready to get some primer.

Thank you!

Moving on with the paint job, it's the same process on the body. Primer, filler, high build primer... Yeah... You’ve already seen this once.
Image
Image
Image
Image
Image
Image
Image
Image
Image
Image
Image
Image

Then the body got to come out in the sun and get its first wash. The biggest difference here was made by the iron remover, which turns purple when it reacts with metal particles.
Image
Image
Image
Image
Image

It makes a big difference to remove those brown spots, as you can see on the driver’s door...
Image
Image

The overall look instantly becomes much nicer!
Image
Image

Then something I’ve been looking forward to—removing all the stickers on the car. Some people will probably be annoyed that I’m removing the old decals, but the car will have some kind of reference to the "Expressen wasp" in the future.
Image
Image
Image
Image
Image

With the body washed and the stickers gone, it was FINALLY time to polish! Unfortunately, I had so much fun that I barely took any pictures during the process...
Image
Image

So instead, you’ll get pictures of the final result.
Image
Image

There’s not much left now before episode 3 is ready. Until next time!
