Just an FYI, I recently "refreshed" my rear light sockets. Typically, they're packed with what looks like peanut butter, but is really just a 30-something-year-old grease. It wasn't by any means a quick job, but I was able to get them looking pretty much brand new and packed them with fresh dialectric grease. Lots of picking, scrubbing, then more picking and scrubbing. Totally worth it in the end though. I'm actually considering selling sets of them and charging a core, so I could constantly be refreshing them and getting them back out to MJ owners. Here's a before and after of how they look!
