Back when I was neck deep in Eve, I was one of the first to jab myself in the butt with a syringe full of pod-be-gold. I received a lovely permanent ... gold - I guess - plating. I liked it. Sleek and sparkling, it glittered in the starlight. However, today, when I decided to strip from my ship and admire the glittering reflection of my pod, I noticed that its butt was a bit... well... pewter.
It must be the angle.
The simplest thing to do was ask. With a question asked and an answer received, I was now the proud finder of ship washing. Eventually. It took me a few minutes.
I hit the wash button and my pod looks exactly the same.
