Rear sub frame corrosion MOT advisory

Had this on the last MOT.

Garage said MOT stations are noting this if they see any surface rust.

Also said they can scrape off surface rust and repaint if I want. Advised that new rear sub frames not available so if it did rust through I would need to seek a second hand replacement.

Any views?

Thanks

Steve

XK subframes rarely rot sufficiently to become MoT failures but they can look unsightly. Try using a rust converter (like Jenolite) and then treat the subframes and other steel underside components to a dose of Lanoguard/Wayoyl or similar and repeat every year or two. That should hold the problem in check for a while and it will look a lot better. Mike.
