Pressure wash arches?

How about remove wheels, remove wheelarch liners (a very quick job), clean if necessary, while they're off clean deposits from inside of wings, apply cavity wax and/or underseal, and then put her back together.
 
Hi Neil soulds a good idea does mud get behind the arch liner?

I wouldn't use a pressure washer at all. It forces water into places it is not intended to go and according to recent reports can even damage your tyre sidewalls therefore compromising their structural integrity. Waxoiling the inside of your wings is a good idea though I don't think for a second it will prevent the bottom of S2&turbo wings from corroding.

The most important thing you can do as part of your car washing routine is to take the car for a good long drive afterwards. Not only does this dry off the brakes but it also dries off the inside of the sills. The more I think about it the more i'm convinced the more you drive the car the less chance you have of any sill corrosion issues. This thinking is because the sill is part of your car's ventilation system and relys on air flowing through it, therefore by driving you keep the airflow going therefore dry the inside of the sill. The worse thing you can do after washing the car is to drive it straight into the garage where the moisture in the sills with just sit there working on corroding your sills.
 
IMHO you should never use a pressure washer on a car, they are just too strong. I have had to repair paint damaged by careless pressure washer use so lord knows what it can do to the softer underseal underneath the car
 
Answer... Don't use the pressure washer on a jet setting.i always use mine on all my cars and motorbikes but set it on a 'fan' pattern.

I do this too ... never on the direct pencil jet (here's hoping it is OK!)

FWIW, it is well worth taking those liners out and cleaning behind (with a pressure washer on "fan" setting), then liberally applying waxoyl or dinitrol or similar. I did this on a long hot summers day on my S2 last year, and will do the same one summers day this year. I happen to think that it will help prevent the rust quite significantly. Certainly the first traces of rust on the edges of the front wings have not progressed at all last winter (but then you do struggle to actually see the edges of the wings, given the amount of waxoyl I put on ... )

I've not looked in detail, but can someone advise how you remove the wheel arch liners? Is it obvious when you are in there?
I cleared a lot of caked mud out of the wheel arch when I got my car and can't believe there isn't any behind the liner.

Cheers,

Ian

you'll need to take the front wheels off and then there are 6 or 7 plastic nuts which will be obvious to see and which will need to be removed. The liner should then come out, with some jiggling around to get it past the shock absorber. The liner on mine was also held in place at the bottom by the front bumper and it was all so rusted up that I had to cut the liner itself to get it out, but you cannot tell once back in place

I would be more inclined to use underseal on the wing behind the liner than waxoil. I would expect waxoil to wash away pretty easily in that location from the water spray from the front wheels. Certainly waxoil is okay inside the cills.
 
Thanks Phil. Sounds like its well worth doing. Can you get access to the cills with the arch liner removed?

What about the rear - is it similar?

Cheers

Not particularly but it's a great opportunity to wax the underside of the wings, look for early signs of corrosion, check the condition of the ABS unit (offside) and the horn assembly (nearside).
 
The mud actually settles on the return lip under the front wings.

Clean it off, prime it/rustkill it and waxoyl it. It shouldnt come back or get worse.

While you`re there waxoyl the brake pipes and the abs unit

you wont be able to access the cill from inside the wheel arch. Open the door though and there is a black plastic vent below the door catch. Romove that and you can access the cill from here. I have waxoiled mine with an extension lead.

The rear arches don't have liners so are not such a problem. Make sure you keep the lip directly behind the rear wheels clear of mud though
