Steel subframe protection

Recommended Posts

Just a thought for all our XK X150 owners out there.    Have you had your steel sub-frames treated?

The X150 XK (Ian Callum designed) is of aluminium construction, unlike the X100 XK8 which is steel and has many hidden rust traps.    However, the front and rear suspension mounting frames are painted steel, and they can rust.   We are aware of a 2008 X150 where the entire front and rear sub-frames had rotted through.

Whilst having a minor job attended to on our X150 this week, it was suggested that our sub-frames be treated with Waxoyl to guard against any potential corrosion.

Now our X150 is 2007, has covered only 9500 miles from new (we bought it in April 2016), and lives in a Carcoon.  We try not to go out when rain is threatened, but you do get caught out occasionally.    We were delighted to discover that our subframes are near perfect, but we had them treated anyway.    Our man said that the slightest chip or flake on the aforesaid sub-frames results in the paint lifting quite rapidly, so over time the rust could get a hold.

We were also pleased to discover that all the various plastic-coated and paper labels underneath the car were still in place!

Now we are all set for another coat of Carnauba!   Happy growling

**As a postscript, we have decided to return with our '07 S, whereupon our man will remove the sill covers and examine and treat the sills within.  Prevention is better than cure, and, as Joe.dot.com says, relevant to the S-type............"Sills, sills, sills!"

hi

you want some thing like a waxoyl or cavity wax, if you use waxoyl, make sure you dont put it on too thick, when its thick it goes hard and cracks, water gets behind it and makes things worse

cavity wax goes on really thin and stays soft

but if it were mine I'd take it too " KROWN RUST TREATMENT ", superb job and its guaranteed

they really do a great job, worth every penny and protect your car for the future

I know quite a few people that have had the alloy xj's and xjr's done, alluminium bodies can rot faster than steel and where steel bolts to ally, they corrode faster as you get a reaction

cheers

Joe

Spot on Joe...............the place (near Witney....yes, we are happy to travel when we trust the service!) who did our XK's suspension mounting frames used a thin coat of Waxoyl and checked the various points where aluminium and steel are in contact.   No issues at all.    

Although the XK lives in a Carcoon, we shall return in about 18 months for a remedial check, and so on going forward.

We are very interested to see what happens with our S - it was, according to the 1st (and only other) owner, treated when it first went on the road in late '07 (it was a Jaguar Mayfair showroom car for a while).   Fingers crossed!!  We'll post some pics once the sill covers are off.

Ron, we have enrolled you in spelling/predictive text classes.  What a sillsy billsy you are.  Go and polish your leaper as a punishment.

As always, happy growling.  P.S. We had great fun coming back from Witney on Friday, trying to keep ahead of the rain which loomed ominously in the rear-view mirrors.    Just made it, although it was a close-run thing around Moreton-in-the-Marsh etc!!

Thinking back many years, MOH says he did his Range Rover Vogue ('90 G plate) with waxoyl and put it on too thick.  As a result, things did get worse............lesson learnt!!
