I have a newly purchased 2010 XKR Convertible. When I returned home from receiving the car (9 hundred mikes away) I put on the rack in my shop to inspect the underneath of the car, Thankfully it's as nice as the top (excellent) with the exceptions of several small instances of the protective anticorrosion being scraped away and exposing the aluminum to the atmosphere. Does anyone know what this coating is and can you suggest a source in the US?

Yes the steel subframes on Jags seem to be very poorly protected with just a thin coating of black paint. Rust is starting to form on my XE's subframes just 2 years from new. I use Hammerite Underseal on the underside of all my cars and it does protect well because it stays soft so doesn't chip or come away from the metal. You can get at exposed parts of the subframes to coat them with Hammerite but that leaves large inaccesible areas which would really need the subframes to be removed to get to them. It's very disappointing that Jaguar don't protect their subframes better - you really should expect them to be powder coated at the price points that Jags sell for.

Some use Dinitrol, some use Lanoguard and some have the subframes removed and powder coated, the choice is endless really.

Lol chance would be a fine thing, although you'd think, wouldn't you?

As others have said, M100TWO and #Steve that I know of have used ACF50, a lot more that I know have used Lanoguard, which I intend to use myself at some point, hopefully before too late lol

The go too back in the day was always Dinitrol or Waxoyl.

Choices galore BobinHSV........pick one and go for it

if any of you guys are motorcyclists in the UK you will have explored most of the rust protection options - any failure is much more noticeable on a motorcycle than the underside of a car. ACF50 is good in that it can be applied with a misting spray (and there are specialist firms who will visit and do your bike for you). So the mist is good because it penetrates all the nooks and crannies, but it's pretty useless in high exposure areas, and I would guess that the xk subframes are in this category. You could make it work by re-applying it in winter every couple of weeks, but in order to do that you would have to effectively clean off all the salt and crud, and in the process you may also wash off the acf50 in the nooks and crannies where it is still doing some good. This
is one of the more useful tests of corrosion inhibitors, and as a result I'm using XCP Clear at the moment. I previously tried the slightly better XCP original but it had the disadvantage of making everything look rusty because it's rust-coloured 😄. But it would probably be better for the underside of a car. Can also be misted if you wish.

Dinitrol ML is good for injecting into the inside of the subframes and cross braces, then lanoguard or fluid film style spray, which is probably more accessible in the USA, on the outsides.

Make sure to soak some well around where the cross braces bolt up to the underside as they do suffer some bi-metal corrosion between the steel and alloy.

For the damaged undercoat on the alloy sections you mention, something like Dinitrol 4941 would do for patching that up but it's less of a concern than the steel work.

Fortunately, my car has never seen salt or bad road conditions. I was a northern "summer: car. Parked in a heated storage area from November til May every year. Only driven in good weather, usually on warm summer nights with the top down. Underside of the car appears as it did when new, 13 years ago, except for the bottom chassis scrapes in 3 places.. Now being in Arkansas will be basically in the same condition as before. I go to Costa Rica in early December, store the car in my shop, and return to Arkansas in March/April. Car will only be driven in nice weather unless bad weather catches me out....
