I have a bottle of Thin CA glue that has become very thick. I have left it in my shop with the top off since I got it. It is probably around 6 months old. It seems that it became thick just in the last couple of weeks. I don't know if it is because of the heat or not but I'm guessing that is what caused it.
My question is, can I thin it down with acetone or will that degrade the adhesive properties of the glue?
