Biohazard

Actually, there are a total of 4 springs and only one did NOT have the yellow paint on it!

Gerald, the stink resided primarily in the soft goods with the fibrous insulation being the worst of it - particularly since it is distributed all over the car. I mean, you're talking floor, cargo area, ceiling, behind the dash. Then, of course, there's the seat foam. It's all history, now and the only odors in the garage now are from the fresh paint on those seat frames. If it were warmer, I'd have left 'em outside and/or they'd be done off-gassing already.

The nuts that secure the seat tracks were very grungy but they were left to soak in that engine cleaning sauce for a couple hours (I sorta forgot about 'em) and all of the crud pretty much fell off when I held them under rinse water.
