Hi guys,
I've read quite a bit on the whole rust problem with the minis, but havn't been able to find anything on reemerging rust after it has been fixed (if there is a thread could some one link it to me?)
Anyway, this has what has happened:
Brought my car in januaryish to get the rust on the door sills fixed, they approved it and did it all under warranty. came back looking fine.
4-5 months down the track, i look again under the rubber door sill and what do you know, rust has appeared again! has anyone else had this problem of reemerging rust?
I was wondering are the rubber sills meant to keep water in or out? because when i lift the sills up water flows out (both before and after it was replaced when i had the rust fixed).
Also, if the car is properly galvanised what is the reasoning for it to rust ? Should it not prevent corrosion even in a damp environment (ie under the wet door sill)??

 

Sounds like the rust was not properly neutralized. You have to use something like dilute phosphoric acid to neutralize the rust at a molecular level. Sounds like a return trip to the dealer is in order.

I am not aware that the car is galvanized (properly or improperly). The car just has a corrosion warranty. Obviously, there are anti-corrosion steps that have been taken during the manufacturing of the car. But galvanizing? You may be expecting a bit too much. Galvanizing will not absolutely prevent corrosion - slow it down, but not prevent it.
