Since the restrictions on Corona have lessened, I managed to drive the NSX more frequently and figured out that my engine glass damper isn't working sufficiently anymore.

There are some entries in the forum that state that they got recharged, which sounds like a sensible approach to me. Unfortunately, when searching for such services online I couldn't find a company in the EU that provided such a service. Since it might have simply used the wrong keywords I wanted to ask for advice how to identify such shops?
