Wire brush first followed by Hammerite and then some waxoyl.:mrgreen:
Underside rust - acceptable?
I recently clipped a newly-installed plastic speed hump and as a result had a closer look underneath and took a photo.
I was surprised how much rust there was on the flat girder thingy that runs diagonally across the photo. Is this normal for a 2006 car with 70K miles? It's not garaged; should I get it wirebrushed and waxoyled before winter sets in?

I’d remove the brace off the car and do a proper clean on it, protect it and re-fit.
Thanks, I'll pop into my local garage and ask about it. I hadn't realised the offending parts just unbolted though, I thought it was structural. They can have a look at the rest of the underside too.
I think Chiltern could have attended to this before sale as they make a big thing of 'prep' - but I doubt it's a warranty item and even if it was, hardly worth two 5-hour return journeys.
How would the cost of refurbishment compare with the cost of new braces I wonder?

There's an A-frame at the front end and a K-frame at the rear, both just bolt into place. Mine look much like yours after 9 years and about 93k miles. I've taken a wire brush to a few places like that underneath my car, it comes off easily and appears to just be surface rust. It won't be a warranty item as your original manufacturer's corrosion guarantee will have expired and no third party or aftermarket approved warranty I've ever seen covers you against corrosion.
If you can get the car on a proper lift and attack with a wire brush then that wouldn't be a bad start but the better way to do it, as Ian suggests, would be to get a fresh set of bolts/nuts/other fixtures and fittings, remove the items in question, brush them back, seal and treat them and fix them back on with the fresh bolts etc. The opposite end of the time+effort=reward scale would be to get some Hammerite Rust Encapsulator and just spray it on; it seals rust up so it doesn't get any worse. If you're sure enough that it's just surface corrosion then that's probably safe enough.

Great reply, thank you. I'm not going to be crawling around in a 6" gap getting rust in my face, this will be a garage ramp job.
There are two garages locally. The first one said they could do it but only brush and waxoyl; they didn't want to use any paint/rustkiller for some reason. Second garage is ringing me back tomorrow. Either way it will be a good chance to have a thorough check underneath and make sure there's nothing insidious elsewhere.

You're just not cut out for this whole Jaguar thing, are you...I'm not going to be crawling around in a 6" gap getting rust in my face...
My idea of the Jaguar Thing is to waft about in silent magic-carpet leather and walnut luxury... if I wanted rust in my face I'd restore steam trains!You're just not cut out for this whole Jaguar thing, are you
I hope Jaguar relaunch the 'grand tourer' class one day, but I fear it will just look like a squashed XF.
..hmm...
In fact I thnk I just designed the next XK - where's my cheque Mr Tata?

Thats a good point you make Simpo in your last sentenceThanks, I'll pop into my local garage and ask about it. I hadn't realised the offending parts just unbolted though, I thought it was structural. They can have a look at the rest of the underside too.

Here's the prices and part numbers for the braces:
Front Brace C2P24220 - £215.64
Rear Brace C2P24970 - £214.06
Both prices incl vat.
I'd purchase all new bolts/washers etc on top of these for peace of mind.

Thanks - where would be the best place to get them from? Presumably not a Jag dealer...Thats a good point you make Simpo in your last sentence
Ian's given Jag part numbers and prices above. I'd still remove the existing ones and try brushing them down and sealing them first, then reinstall with fresh bolts etc., save yourself over £400.
Wow, just seen those prices. That's a lot for two girders...
Just spoken to another local garage who can look it over next week - they won't do Waxoyl due to the mess but recommend 'chain oil wax' which is new to me... anyone know this stuff?

Not sure what that might be but I know a lot of bikers and people like Caterham or Ariel owners use something called ACF-50 - http://www.acf-50.co.uk/motorcycle.htm
I might give that a shot before the roads get salty up here this winter...

I use ACF-50 on my duke and whilst it's good stuff I wouldn't use it as an alternative to waxoyl or similar. It's used in the aircraft industry to prevent rust and leaves a clear protective coating. It's nowhere near as thick as a wax or paint coating and needs reapplying before each winter which would be a pain for where you want to apply it. Not cheap at £15-£20 a can either.
does what it's meant to do in all other regards though!
