AAGH - Rust

[rhitchcott]

I've just spotted some rust on the door pillar by the rear window.
Has anyone else seen any rust on their cars?

although some of these cars are fully galvanised the weak spots i have noticed are ,,

tailgate latch pins , also where the tube goes out of the rear wheel wells for latch pins , sunroof drainage points , battery tray , rear quarter windows near pillar water collects there , inner wheel arch where indicator wiring goes through to fusebox , the rubber ring often comes free and allows water in when driving through puddles easily sorted , other area to check is the drainage points where the battery is located they get filled with leafs and small children ?

so that's what all the hollaring under the bonnet was..

Rust is unusual in 1980 onwards 924's but quite common on earlier cars.
I have 2 1982 cars and the only time that they spend undercover is if I drive under a bridge. They have no rust despite the neglect. On the other hand my 1974 911S that lives in a dry warm garage requires welding every year for the MOT.
That's the difference between a 924 and a car costing ten times as much[]

Actually, thinking about it for the first time in 13 years, how long could one expect the body to last in 'ordinary' conditions without significant repair?

I only wanted to keep it for a short time when I got it, but it just keeps lasting..

We have had our 924S(1986model) since 1991 and have yet to see any rust and it stays outside half of the time.
However,last year at it's MOT in my absence,they must have raised it using a 2 post lift and crushed the cill flanges somewhat .This had cracked the coating so I have repaired and straightened the areas,rustproofed and multipainted them to avoid future trouble.
I always carefully spray inside the wheelarches and clean all the mud off where it sticks against the turned in flange when I wash it.Others have covered most points.

Hmmm, I have an A plate which I am now going to repair fully, get a full mot on, and then advertise as can't afford the car and house and baby all together.

There is a small blister appearing above the sill, and I want to repair it properly, so what is the procedure for a galvonised body? Is there any special treatment I need to get on the metalwork once I sand down before priming and painting? Once I get any abrasive material onto the metal, won't this remove any protection which has been applied during manufacture?

Any advice much appreciated.

once you have cleaned the area it may be a good idea to apply rust eater as i have found that it helps the rust coming back , and a good plastic primer over that then paint . it doesnt react with the primer or paint . i will have a look in the garage a little later to find out what the make is for you . )
