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?
