It is about time to add fluid to the brakes and clutch on my '67 Sprite project. I know the usual suggestion is Castrol LMA and I have always used it in the Prefect, so far with good luck. I put silicone in the VW years ago, however, and it has performed flawlessly. I would like to at least consider if for the Sprite mostly because it doesn't eat paint if there are any leaks. What is your thinking?
