Master cylinder covers

[conedriver]

I have seen race cars with a shop rag secured over the clutch & brake master cylinder reservoir caps to catch any brake fluid that might leak out during extreme cornering forces. My autocross Spider tends to do the same thing, and I'm looking for a better solution than a shop rag. I have seen commercially manufactured elastic "booties" obviously made to fit over reservoir caps, but can't find such a product even after a thorough search. Does anyone have any hints for finding such a product? (I think this might be an Asian car "street racer" item...)

George,
Have you tried Dave Bean or Pegasus?

Tennis wristbands work, depending on the size of your reservoir. On the early round Alfa reservoir you also definitely want to run the rubber bladder.
