CA Problems
I've had a couple of CA incidents that I hope someone can help me remedy.
I hinged my tail feathers that were covered with transparent monocote but not yet installed. After anchoring the hinges with a drop of CA, I left them lying on top of each other overnight. The monocote of my vertical stabilizer is now stained with a foggy white residue where it had been lying on top of the not quite cured rudder hinges. What do you recommend I use to remove the residue, or shoul I just re-cover it?
2d question: I was attempting to scrape off the tip of some thin CA. A particularly stubborn area caused me to really bear down on the tip, causing it to break free and flick, covering one lens of my glasses with tiny CA droplets.
The lens are a "feather-weight" polycarbonate material. Washing does nothing, scraping with fingernail doesn't move them. Scraping with edge of plastic credit card seems to leave scapes on the lens. Suggestions?

Several mfgs produce CA "removers"Use this stuff as directed and it should soften the CA enough to remove the drops on your glasses,but I dont know if it will affect the lenses.If the glasses are expensive why not ask the folks where you bought them?

CptCrunch,
Anything CA gets on that it does not stick to can easily be scraped off with your finger nails, check with your lens mfg, you may have etched your lens (better the lens than the eye).
If you have the plastic lens for working with, I would consider getting a good pair of safety glasses. They are cheaper to replace --- in most cases..

CA debonder does work well for this fogging, I call it etching. It's the fumes from the glue. Odorless CA does not "fog" to this degree I don't believe. Monokote TrimSolvent also works well for cleaning this fog off of monokote to the point you will never know it was there.
As for the glasses, not sure what to tell you. You might try either one on something similar to make sure first. Although if it cleans monokote without a trace, it just might work.
The key I've found is let the chemical do it's work, don't try to force it. It's the rubbing that could do more harm then the solvent/debonder. I use cotton balls for the applications on monokote. Good luck.

Acetone will clean up the residue in a heartbeat. It is cheaper than debonder, and actually, it is the same stuff.
If you want to be official, take an empty CA bottle and prepare a sticky lable that says "debonder" on it. Then fill it with acetone.
You can buy acetone for 3 bucks a quart in the paint department at Walmart, or you can buy CA debonder for about 3 bucks an ounce.
Acetone will clean up any epoxy you drip on the plane while attaching the empenage too.
After covering, wipe the airplane down with Acetone to remove any adhesive that oozes out while you are ironing down.
Use acetone to wipe down any oil soaked parts of the model prior to repairing after a crash.
Acetone softens CA, but once the Acetone evaporates, it will leave the CA intact.
Do besure to ventilate the area. Acetone is not friendly to brain cells. Which is why your sister in law, the one who does her nails three times a day, is such a ditz. Until about three years ago, Acetone was the working ingredient in her nail polish remover.
While you are at Walmart, pick up a quart of denatured alcohol. It is a safer solvent to have around, and a good one to try before haouling out the acetone. Denatured alcohol is perfect for cleaning up epoxy before it cures, and it does a great job of degreasing monokote before you patch holes.

Hello!
I agree that Aceton is rather good to remove CA glue and that debonder is just a big joke....!!
but it is not the best metod! Better yet is Nitromethan! This disolves CA faster than any debonder and faster than Aceton and it could be used over every plastic covering-film on the market.
Ofcourse you have to take a papertowel and polish real hard to get rid of the Ca glue ...not just put some drops of either Acetone or nitro on...!
Some hard work is always needed!

Well, I tried removing it myself and screwed up the lens. Don't try scratching it off with a plastic credit card. Leaves scratches--Duh!
Now the good news: I found out that the lens were covered for 1 year from scratches and cracking. Luckilly, Lenscrafters honored it.
Hotwings is absolutley right. If you get something like CA on eyeglasses, take them back to where you bought them. They told me they've safely removed CA, and much worse, in the past. They know what's in and on the surface of your glasses and know what they can and can't use. Don't go trying any home brew methods.
