I've used spider wire (stranded fishing line), floss, and on the Stinger, a piece of a nylon strap from around a crate I had in the garage (I ripped a thin, thread-like piece from it).
The key is to only "pull" against the
badge, never any rubbing against the paint. There's a ton of room there. On the Stinger, I had a can of WD40 handy and used that to lubricate, which may or may not help. No idea if I bothered with anything like that on prior vehicles, it's just not difficult.
Used to meet a group of riders down at L5 Pizza on Thursdays. Getting down there in traffic was fun even with being able to use the HOV lanes. I'm not afraid to ride in traffic but have to say that was probably some of the riskiest riding I've done.
Much prefer Planet Bombay, but there's always one or two in a group who "can't eat Indian food".. and you can sit outside at L5P..
