oil stains from Thayer valves

[fsgazda]

I guess this should go under this topic.............

I recently switched to a set of stacked dependent Shires Thayer valves (which I am quite happy with).

Problem is, they are leaving oil stains on my shirts. I had the same issue with my inlines, but there is a leather specialties company neckguard that fits. I can't find one that will cover the 2nd valve (which is where my problem is.

Anyone else play dependent Thayers and have a solution?
