I couldn't even paint them in good conscience the way they were. I'm not sure the picture really does any justice of how bad they were. There was years of carbon, then a (bad) paint job, and then years of carbon again so there was a visible texture. It would have looked like I slathered the inside of the tips with concrete, and then painted it :-p
I was pretty surprised to find it though. Everything else on the car is in very good shape.
