Yesterday I spent two+ hours scrubbing into the corners of the rims but the front ones still have little rusty lines in the sharpest corners - I'll try a polishing bit on the Dremel for that, as I guess the laquer will already be breached.

Apart form that, all is good - starting, shifting, AC, suspension, braking all like a champ, CD changer changed (for the older style with the BMW logo as I blew up two of the Alpine changers) with subwoofer and all speakers hot - best of all I managed to pick a HU out of the dusty pile of parts in the workshop and it turned out to have a pixel-perfect screen and working illumination and volume pots - I'm praying that todays' passenger door lock and window lifter change will be the last for some good while!
