Continuing an unplanned "work on the Boxster" weekend repainted the wiper arms flat black and installed new wiper blades using the "towel method". I've included a picture here for folks who don't know what this is.
The folded towel is there to protect against the end of the spring loaded wiper arm breaking the windshield if it accidentally snaps closed and hits the glass. Apparently more than one forum member has lost a windshield that way which is how I learned it.
