Cavity waxing a Boxster

[pothole]

Thanks Brad, take you points.

One thing I'll say is that 944s with really rotten sills are common here in the UK. I doubt that's because they've all been mucked about with. They just rust. All steel body cars rust.

No argument, Pothole - all steel cars can rust. In Canada, many people drill holes in the body cavities of older cars and have oil sprayed throughtout annually before the winter. As with traditional rustproofing, the holes are then plugges with removable plastic plugs. It leaves one heck of a mess beneath the car for awhile until the dripping stops, but at least oil will put a coating over existing rust which will dramatically slow the process. It is somewhat akin to coating iron/steel tools with oil prior to storage.

Care must be taken, however, as I am unsure how the oil would react with the existing wax/based coatings on the Porsche!
