Oh and I forgot. "Goo Gone" citrus based cleaner will probably knock
this straight off. Maybe followed by a clean wipe of 3M cleaner,
acetone or toluene, etc. I've used Goo Gone to take off residue of
misapplied stripes similar to Monokote.

xylene (xylol) is very effective at removing adhesive goo when all
else fails. It's usually available in pints at the local big box
hardware store.

Hexane is good for contact cement removal, assuming its not been banned
as a VOC. It was the best of a fairly unimpressive set of solvents when I
needed to clean double sided tape off some mylar gap seal.

Pretty sure it's 'unobtainium' now. I could be mis-remembering, but I
think I used Hexane as an additive to fuel for my compression ignition
engines.

That would have been ether, assuming you mean model engines: 40% ether,
20% castor oil, 39% kerosene, 1% amyl nitrate runs pretty well.

Outside a lab I've only seen hexane sold as thinners for Evostik contact
cement.

Xylene is one of the main ingredient in the 3M General Purpose
Adhesive Cleaner, and yes it does work well for many things. I think
the 3M blend is pretty handy for removing stuff (including wing tape
residue). However the original poster reported it did not work in
this case. From the material safety data sheet the main ingredients in
3M General Purpose Adhesive Cleaner are

XYLENE 30 - 60%
NONANE 10 - 40%
OCTANES 10 - 30%
ETHYLBENZENE 5 - 20%

I've been able to purchase this even in California, e.g. at my local
Orchard Supply Hardware store.

I have had good result removing all kinds of decals and "stuff" off cars and
motorcycles with "GO-JO" hand cleaner. It takes a bit of rubbing, but it
is harmless to whatever is underneath.

And in a hurry, I have used the Go-Jo with pumice - it may leave a slight
haze, if what's underneath is not too tough.

Monokote is fuelproof so run of the mill methyl and ispropyl wont
work. That's what fuel is(methyl alc). Try Acetone and I recall
there is a TopFlite Monokote solvent that you could probably get at
towerhobbies.com.
If that does not work, let everything evaporate and no longer
flammable and gently use a heat gun and putty knife to scrape it off.
Any remaining residue can be wet sanded off.

BTW, standard disclaimer with all this solvent talk, try on a small
patch first for compatibility... Gelcoat is pretty stable and can
handle Acetone, but not sure if glider in question has polyurethane
and what it would do.

Once had a friend who put some solvent in wax paper cup and set in on
the hood of his 280Z while he worked on some blemish. Meanwhile, this
stuff ate through the cup, and then proceeded to etched the paint job
on his car hood.
