Do you leave it plugged in 24/7? The preheat system I have (Reiff hotpad)
recommends against leaving my airplane plugged in 24/7 because of rust
concerns...

It depends.

If we are on our normal flying schedule (every couple of days), yeah, we
just leave it plugged in.

If it looks like we might not fly for a few weeks, we don't.
