Monokote trim patches for covering holes - not recommended

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.

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.
