This weekend I Waxoyled the sills. Despite having the car for 9 months, it was the first time I had the sill covers off, and I was nervous about what I might find. I knew the sills were solid - I have been using them on a near-weekly basis to jack the car up and down and I haven't seen anything untoward, but until the covers were removed, there was always a question mark in my mind!
I needn't have worried, the sills were better than I could have hoped. The driver's side didn't have any surface rust at all, the passenger side just had a small patch about the size of a playing card and the rear edge was getting a little flakey. I cleaned it up, brushed on a coat of waxoyl on the outside, and sprayed waxoyl into the inside as best as I could with a rattle can. I think I might do a more in-depth treatment in a year or two, but this was more of an initial investigation and basic treatment.
(The can of Dulux is forward of the front axle and just holding the tarp down, it's not - as my wife thought - holding the car up
)
Unfortunately the sill covers are starting to show significant bubbling on the inside, about a foot in from either end, and the ends themselves are getting a bit tatty. So I'll look to replace those in the next year or so. In the meantime I gave them a coat of Waxoyl on the inside and refitted them with new hardware.
Other than treating the sills, I took a trip out to meet up with
@Andyboy and relieve him of the M54B30 intake manifold & cam he was selling. They've gone on a shelf in the garage along with the E46 330i front calipers I bought from
@Delk a few weeks ago. I'll look to start gathering more parts and fitting those in a few weeks when we're back from Spain
) and managed to get the intake boot fitted.
