Monokote trim patches for covering holes - not recommended

[Uncle Fuzzy]

A while back I posted that I had used Monokote trim to cover some of
the larger holes in my Speed Astir fuselage. They did a nice neat job
of covering the holes, but here's the follow-up. I removed one a
couple weeks ago that had been in place for a couple months. The
mylar pulled off cleanly, but left the adhesive behind, and boy howdy
was that stuff difficult to remove! Perhaps with the RIGHT solvent,
it wouldn't be a pain, but the 3M General Adhesive Cleaner doesn't do
much but make it gooey. If anybody knows what sort of solvent would
work better on the Monokote trim adhesive, please chime in, cause I'm
sure the 'racing checker' patches made my glider faster!

I remember when I was a kid building RC gliders, sometimes the tinted
adhesive would seep out from under overlapped seams.
I took off the residue with 91% alcohol I got from the drug store.

Mind you, that was around 30 y/ago. Possible the newer stuff has a different
adhesive but I reckon its worth a try.

Why not just ask the factory?

D'oh! Good idea. I must have made a pretty thorough mental
disconnect from modelling (I only did it for 40 years or so) when I
got into soaring!
The 'edge seepage' from the IRON ON Monokote comes off easily. It's
the stuff from the trim Monokote (press on) that's giving me trouble.
I'll see if I can contact Top Flight.

Many model covering manufacturers make an adhesive solvent that will
soften the adhesive on normal covering so you can use it as trim
pieces. I suspect this also cleans up the trim parts as well. For
example Monokote has one see http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXHZ43

If 3M cleaner did not take it off, I'd try acetone (which is also in
the Monokote solvent).

I stopped by my local sign shop and they turned me loose in their
"scrap box". The 3M vinyl is great for covering up bolt access holes
in my Cirrus fuselage. They have great colors but white seems to be
my old standby.

Carburator cleaner in the spray can will get just about anything off.
It seems that damage could occur however, it evaporates so fast that I
find that as of yet, (knock on fiberglass) I have found it to be
effective and without damage. Try a hidden spot first and try at your
own risk as this is not the normal use for this product. I used it to
get some cloth gap tape off that was firmly attached.

Try WD-40, and a plastic scraper (I used the end of a plastic ruler) and
plenty of paper towels. Saturate the adhesive with the WD-40 and it
will become gooey. Gently push the glue along with the plastic scraper
until it makes a gob that's big enough to pick up with your fingers
using the paper towels. You'll need to work one area at a time as the
WD-40 evaporates. When you're done use some cleaner like 409 or windex
to remove the residual WD-40. I've also used WD-40 and the softer paper
towels to very gently remove tape residue from yaw string tape.

Uncle...

The active ingredient in many adhesive removers is Toluene. You can buy
this from Ace Hardware in quart cans labeled Toluol. It is cheap and it
works. Use it outside to avoid breathing it. I also wear gloves to keep
it off of my skin.

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.

[flash]

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.

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.

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.
