Nice on Marv, nice to see people work on these rather than chuck them to Munich Legends et al

What clamps did you use marv? Heard varying reports on a lot of the aftermarket options.

My e36 ones are fine but expect they’ll fall to bits at some point.

And yeah, they weren’t a great idea, a lot of people have found that the corrosion spreads and eats away the end of the stainless pipe too.

And to bring things back to earth, Civic MOT this week, failed on rear ARB bushes, track rod end bushes, number plate light.

Expected age related stuff on a 16yr old car to be fair. Rad has a weep too, he thinks, although temps are spot on. Got it booked into a local Honda tuner next week as he's got a 2nd hand ally rad, and he'll do a proper inspection on the suspension for me. Can see me getting a bit done on the car £££

I did a bit of research too and like you say, there's mixed reports on alot of the aftermarket clamps.

I asked Redish what they recommend, in the end. They pointed me at the X8R clamps, which seem to clamp the pipes together correctly and seem really good quality:

Sensor and brackets came off easily, but the ball joints were very much seized:

Brackets were de-rusted, new sensor and balljoints, along with stainless fixings. Silicone grease put in the ball joints to keep water out:

What did you use to de-rust those?

Excellent work [mention]Marv[/mention].

these were the ones I used (not my pics). A guy at ProTyre in Slough did me 4 for £10!



But then mine was a 140k mile £8k daily driver rather than a cherished classic CSL!

I use an ultra sonic cleaner, with a citric acid solution.





Strips off the rust quite nicely. I'd like to plate things really, but a layer of zinc primer and spray can paint lasts for years anyway!

If you don't have an ultrasonic cleaner, Bilt Hamber Deox-C does a similar job (albeit a bit slower)

For larger stuff that I cant fit in the ultrasonic cleaner, I use a poly abrasive wheel like this:

They at least saw your E46 through until the end

Nice work Dan and Marv. Nice to see others at work. After my extensive stone chip repair session earlier this year (whicih was a largely worthless exercise!) I've done bog all on cars for some time.

That is one rusty hammer!

Hadn't heard of ultrasonic cleaners. Seems like you can buy various concentrates to use in them. You mention citric acid solution, Marv, do you use a particular one or literally lemon juice in water?

It's the crystallised citric acid:

A table spoons or two of that, in a few litres of water, in an ultrasonic cleaner strips away the rust, as per my earlier image.

Here's my ultrasonic cleaner - things de-rust much quicker if you can crank up the heat! (bought mine through Amazon though, but can't find the same model on there anymore)

I keep meaning to try the electrolysis method of de-rusting but it’s a faff to set up. This looks way easier.

They’re great for cleaning random crap like carbs too.

I want a diy powder coating system, the guns aren’t too pricey and you’d make the cost back after a few uses. Only issue is the oven although a cheap domestic one will accommodate most parts.

I can't wait to hear how you've spent £14k on a spray booth so you saved £200 on refurbishing 4x wheels

I did it a few years ago and it worked brilliantly, but the tub always seemed to be in the way.

I just used an old car battery charger and a bit of old stainless steel pipe.

You’re not supposed to use stainless because it gives off nasty gasses or something, but as mine was outside I didn’t care and it meant it didn’t erode away like a mild steel one does.

The next chemical type thing I would like would be a zinc plating kit like the BOM guys use. Cleaning and de-rusting parts is pretty simple, but it would be nice to get bits back to the oe bright zinc or yellow passivated finish.

190 miles around Wales in the pissing rain today. More proof if proof be need be that the full hood is essential. It would be shit with a half hood. Everyone else is clearly DIW

Would've been fine in a half hood!
