Hi, I have severe CA glue allergies. While using CA for a few hours my nose starts to run. It runs more and more severe so I am not able to sleep. Then I become flue like sick for a few days. I was at the point of completely dropping to use CA. It is however not efficient to work on rigging unless using a CA. So I kept trying different brands and reading about CA glues. Finally I learned of existence of ORDORLESS CA glues. They are rare and expensive but I tried the STARBOND THIN ORDORLESS. To my surprise it did work for me. I work with it about 6 months and no allergies. Glue also has different and useful properties. It does not dry instantly as all other types. It remains flexible after it solidifies - great and rare property for CA. I use home made applicators made out of paper clips wire. Just cut a small slot on the wire tip with a jeweler's saw. See picture. I made many of them. When they get contaminated, and this happens very quickly, I drop them into a small jar with some pure acetone. Acetone dissolves and cleans my applicators. I made up a CA bottle holder from wood which holder prevents overturning of the bottle - very important accessory!
