When I bought my plane it had a few VG's knocked off from fueling. Since then I have lost another one. There is a lot of super glue left on the wings from the previous installations.

My question is, do I leave the residue on the wing fabric, and just scuff it up and put the new VG's on top of the old glue(obviously the glue is well bonded to the wing, it's still there). Or, do I use some kind of solvent (This scares the shit out of me) to take the super glue off and then re-attach? I read acetone will dissolve the super glue, but I'm sure that will destroy the paint as well. I know that just bumping the fabric with anything remotely sharp can take paint off so I really don't want to do too much scraping around on it.







Anyone dealt with this issue?

I'd just super glue right over what you have, what's the worse that can happen? You are correct, acetone may take the finish right off down to the fabric. You could find some out of the way place on the belly and test it to see what happens.

FWIW, MicroAeroDynamics uses a different glue, check on their site for that info, it would appear to be a better choice for this application then super glue. But, I don't know how it will stick to super glue! Heck, super glue it again and be careful fueling and call it good.

Super glue doesn't stick very well to itself. You can give it a whirl, but......

Some patient work with a Dremel tool is easier than it sounds. I've removed a few aircraft data plates from fabric this way...almost could not tell anything was there, but the gloss was gone. I used a metal grinder bit rather than abrasive.

The application of dry ice can more or less instantly disbond superglue from a metallic or glassy surfaces. It is so unexpectedly easy, it is like magic. I have absolutely no idea if this could work on fabric with a plastic resin.

The de bonding agent for cyanoacrylate glue (Super glue)is nitro methane, I don’t think your paint would be very happy with it. One trick to remove most of the glue is shaving, using a single edged razor blade, hold it 90 DEG. to the surface and shave it with light strokes, this is an old trick from removing runs in paint after its dried. Or like the man said, glue right over it, what it the worst that can happen. Hobby shops have different thickness of Super glue, typically thin, medium and thick. 409 is a very good prep cleaner for gluing or painting. There is my two cents worth

Thanks for the responses. The VG's are really inexpensive so maybe Ill try different techniques on each and see how it works out. I still dont think I will use any kind of chemicals to remove.
