This past weekend I went down to my shop to dig through my stash of Boxster "Speedster Humps". I've collected 5-6 sets over the years, mostly Arctic Silver. I remembered I had a pair that I thought were still in primer when I bought them off the parts board here several years back. I'm sure all I did was pull them from the packing, check them over, and stick them on the shelf.
I pulled them down, took them from their wrapping, and they were in original factory paint, the same shade white as the car.
So that'll save me a few dollars at the paint/body shop.
