Rust in not so usual spot on front wing

[sentwistle]

I read this forum quite closely and hope to not ask a questions which has been covered before but there still that risk....anyway.

I have some rust on one of my front wings where the valance, bellows attach.

My understanding is this is not so typical. I have cleaned inside the wheel arches all round the car in the past and made an effort to concentrate on those typical areas which do tend to start rusting.

I use JZ's for servicing but unsure if they do bodywork or if they farm it out.

I want to repair the car so it doesn't get worse but can't afford to go the whole hog and do the bumpers, valances and bonnet which could all do with improvement.

Anyway my question is anyone around Milton Keynes area have a suggestion as to were I should go to get quotes for a repair ?

I'm no expert but I've heard that anywhere steel (body) meets aluminium (bumper) and moisture is present can cause rust to appear. I dont know how true that is....Anyone else care to comment?

Steve, I can recommend Roger Olney at Linslade Motor Services in Leighton Buzzard and his number is 01525 374009

He sprayed the front end of my Turbo and sorted out some minor corrosion on the rear wheel arch. He was recommended to me by another happy 944 owner.

His yard is an absolute mess and would put off most people but he knows his stuff and when you look around inside his building you often see a few old classics undergoing restoration

My 89 supersport is mint except for two small rust patches, guess where !
front wing next to bumper bellows . It will get sorted in the winter.

I have shown it to Langley Autocraft and they are sending me a quote in the post. Seems they can cut out the small amount of corrosion and make good. The rest of the wing is in a good state as I have cleaned it all out and checked the "usual" problem areas (around filler pipe, base of headlights, B-posts all look fine).

Does anyone have experience of their work ? I know they are recommended by both JZ's and that should be enough for me, but I wonder as thye seem to be a high volume place who may not understand my desire for a good job.

I've got the usual selection of stone chips on my front bumper and some bubbling on the rear bumper and a spot of rust on one wing.
I'm having both my bumbers, both headlamp surrounds and the left fromt wing removed, prepared and resprayed for about £400.
That's at a place near Canterbury so probably not much good as a recommendation but might be handy as a price guide.

Hi,

On my car the panels in this area are both steel. The rust identified may well be the result of the underbody protection having dried out, allowing water to get to the surface it "protects". Any galvanising protection has, of course, failed. The thread " Bare Metal respray etc" on this forum contains much information on related matters.

Where aluminium and steel come together, Porsche ensure that the area of contact is reduced as much as possible. In the presence of water, steel rusts, but the component that comes off worse is the aluminium. This largely accounts for the all too familiar bubbling on the underside of bumpers in the area adjoining the mounting holes and bellows.

Originally Porsche provided nylon sleeves that were pressed into most if not all of the mounting holes in the alloy bumper. In addition all steel fixings were closed off with a rubber washer, between alloy component and the flat washer and nut, again to minimise the contact between aluminium and steel.

Once the process has got a grip. it is extremely difficult (if not impossible?)to neutralise oxidation in aluminium. The rear bumper in particular is prone to damage of this sort where the heat from the silencer justs accelerates the oxidation process.

This component on my car was quite badly affected by oxidation, although all of the Porsche provided fixings were present. In particular, the threaded holes in the lower section, by which the rear valence is secured with steel set screws (no nylon here) had oxidised to such an extent that the bumper was showing signs of delaminating - the corrosion having established itself between the layers of aluminium. That was a suprise!!

Probably the biggest mistake we can make is to think that our cars will not corrode and that the famed galvanised body will protect our investment. Forget that. Protection best comes from the owner who, having recognised rust and corrosion as a matter of very real concern, does something about it.
