RE: Safely Removing Dried CA from Covering
In the future, it's best to resist reflex reaction by not trying to wipe off immediately and smear a larger area. Once the stream or dot has dried, take a sharp curved blade pocket knife and chip the glue off the covering. Make short little chipping actions at the glue and it will pop right off in sections. Don't try with an Exacto #11 blade or you'll end up with several slits in the covering. This works best on the high gloss film where the Ca doesn't have much to stick to unlike the matte finish film.
