Collection of good BMW e30 rebuild posts

Anyone finding this blog will probably be looking for information on how to disassemble/reassembly some component of a BMW e30. Since I like everyone else spend time digging through the internet looking for gems I figure posting them someplace helps everyone.

This is a work-in-progress and I would  greatly appreciate any comments on other links/resources that could be added to this list (it will continue to evolve):

• Paint stripping, we picked up the Aircraft Paint Stripper and it works well, fumes will kill you though so use chemical vapor mask. Also used Home Depot stripper which worked equally well, go figure. Stripped as much as we could and then used DA sander and scrubbed things down with water and then Acetone. Once the surface was clean we sprayed on a coat of self-etching primer to stop any flash rust.
• Paint, there a few million articles on this, some basics: http://www.popularmechanics.com/cars/how-to/a3110/a-diy-guide-to-painting-your-car-15998013/
