Had my F type for 3 years just had it MOT this was carried out at a friends garage while on the ramp I had a look under neath I was shocked to see the amount of rust which has started forming on the rear diff frame also rust on the cross brace, I feel the price you pay for a car like this components should be powder coated.
Has any body out there looked at these points on there car yet.

Yes. I have the impression that those bits are starting to rust by the time the cars reach the dealers.

I coated the whole of the underside of my car with ACF50 'corrosion blocker' so hopefully it will keep the rust from getting worse. It's one reason why I take my car off the road when the gritters fire up.

That said...These particular mild steel components are just a few bolt-on parts that could easily be taken off and referb'd at any time in the future, so it's not the end of the world. I agree with you however, that for the cost of these cars, they could have made those components out of stainless steel. They're not huge components.

ACF50.

Google it.

Motorcyclists swear by it.

I suspect they are all the same. I bought my car second hand after it had gone through just one winter. In the spring, While I had a rear wheel off I had a look underneath and was alarmed to find the same problem. I agree as has been said. It's hard to accept on such a high cost car. At least the problem is localised. I don't think there's much more steel other than what you can see here.

Thank you so much for sending the photo! It's great to see as I don't think many of us have thought about it. I'm getting that spray soon and making sure it doesnt happen! Smile Great Help!

The day my car left the showroom, I had it up on the lift for 3 coats of 'corrosion guard' to seal the pores of the Aluminium, as there is so much of it. I'm pretty anal about my cars being as clean underneath as on top, as I show it.
The one thing that I did give extra attention to was the rear diff frame. The paint on here was incredibly thin, and if you drive your car in anything other than dry conditions, it will end up like the picture above.
Powder coating is possibly the worst idea, it's brittle and comes off in flakes. Take it back to bare metal, spray it with primer and a few odd coats of whatever colour. Once that lot is dry, coat with your chosen corrosion blocker.
Cars, aren't built to last like they once were. You need to get in early to do preventative maintenance BEFORE they fall apart unfortunately.
Don't forget; If you drive your car in winter, spend a good few minutes spraying the underside of the car with the hose to wash off the salt, up and around the wheel arches, pretty much everywhere as it turns cars to dust!

I've not been under to have a look but this time of year do ensure the underside I can see gets a good clean shower ...

Has anyone approached Jaguar under warranty? The Honda I'd similar construction materials to the Jaguar ... that's 18yrs old and doesn't have as much as the photos below ...

I'm a big believer in making sure the bits you can't see are kept in as good condition as the bits you can see. When you start to look around and see all the electrical connectors, sensors and other gismos dotted around the underside of the car, I reckon it's well worth the effort.
