Any Tips on Removing Epoxy from Covering Film.

Hello, Recently joined two wing half's on my Hanger 9 Corsair which required using tape while setting up. A slight amount of dried West Systems Epoxy was left on the wing after the tape was removed. I have tried acetone and lacquer thinner with no success. Any suggestions would be appreciated.

Thank You,

John

Epoxy is resistant to solvents. Probably the only way to remove it is by sanding, grinding or chipping. Well, you could burn it off but this would damage your wing too.

When this has happened to me, I simply picked it off with a razor blade tip. Be careful not to scuff or cut the film.

yep, #11 exacto, and VERY CAREFULL Kinda put some tension on it, and hold it, and the glue will pull off slowly.

Actually, vinegar will soften epoxy. The acetic acid in the vinegar breaks down the epoxy and causes it to get into a rubbery state, kind of like stiff Jello. If you put some vinegar onto a cotton ball and let is sit on the epoxy for a wile, it will soften, and you can scrape it off with your finger nail. Just be careful and don't let it seep down into a joint, or it can soften that epoxy as well.
