When I was a new owner, one of the early problems we had was the flap
handle not staying put on the C140 - you'd stick the flaps down, and
then usually on short final, the ratchet would disengage and they would
completely retract (even with the rather pathetic flaps on the C140, it
was still disconcerting). Fortunately, the A&P we used wasn't interested
in making us pay for anything unnecessarily. Thinking we'd end up having
to get a new ratchet assembly, I went to him, and he gave me a can of
LPS-2 and said, "Give it a good soaking with this".

The flap handle worked perfectly ever afterwards.

That's the way my A&P is now. When I bought my Warrior in '98,
however, I was dealing with a corporate shop. They would have
insisted on dismantling the entire aircraft to "inspect" the flap
mechanism, and THEN soaked it with LPS-2.

The bill would've been in the hundreds, at least.
