I agree that it does a great job removing grease, oil, and gas stains.
On my plane though, it also seems to be removing a bit of the paint (I
have brown trim and wiping it with E.S.G. with a white rag ends up with
some brown on the rag).

I REALLY miss the overall cleaning and waxing properties of Lemon
Pledge Trigger! Everything else I've tried seems to be "watery", in
contrast to the Pledge "lotion-y".

We use the ORANGE trigger and it seems to work well with the leading
edges. I'm gonna try just plain water for comparison though...

I'll probably just fall back to using plain water ....

This morning I brought along WD-40 and ORANGE GREASED LIGHTNING and
regular GREASED LIGHTNING ($3 for 40oz trigger spray, says aluminum safe
on the bottle) along with the BLUE SHOP TOWELS from WallyWorld. I never
got past the regular GL as it dissolved the belly mess and dripped it
off. Simply wiping with a dry towel removed all the gunk with very
little effort. A bit over half-bottle and roll of towels did the entire
bottom half (everything below the plexi) of a C172 that had been washed
the day before but the belly left for another day. I've shopped around
the stores for E.S.G. with no luck, I won't waste anymore time looking
for it in the future. I'm very satisfied with GL and it would be a
bargain at triple the price...

It did remove oxidized paint, but didn't take off anything that wasn't
already peeling or missing...
