RE: CA STORAGE
I am guessing that your CA is thickening up due to absorption of moisture. Even out of the light, with the bottle uncapped, the air inside of the bottle expands when warm and contracts when cool, drawing any humid outside air back inside. Over a period of time, this adds up and your CA is slowly ruined.
I learned this years ago at a seminar on CA glues at the WRAMS show by a chap who was in the trade. He also talked about storing them in the 'fridge. If its a new, unopened bottle you can get away with it but not as much as we used to 'in the old days'. The reason is, as he explained it, the CA container walls are made more thinly now and its easier for air molecules to get through, once again, to add moisture to the glue and ruin it. It happens slowly, but it happens.
I bite the bullet and buy the small bottles. I always notice a difference between when I use up the last of the old CA and then start working with the fresh stuff.
Just my $.02
