Randy -

It might be it's just the microfiber itself, who know's... The ones I have
called the glosser are disposable, and have some kind of fluid in them,
with supposedly a wax. Whatever it is, they sure work great. I've
scrubbed the leading edges with regular rags, and it's a lot of work to
get the bugs guts off, these things make it a bunch easier. I started
to do some minor cleanup, and ended up wiping down the entire plane
and then waxing it after I finished. Looks ready for a show now, too
bad I'm going out hopping grass strips next time out.
