The CA you can buy at places like Wally World, Home Depot, Lowes, etc is just garbage compared to the stuff you can buy from people like Mannie or even a good hobby store. I tried CA from Home Depot when I first started and quickly learned that even the thicker CA they sell sets up in about 2-3 seconds, not good for gluing in tubes. Now I use 15 minute epoxy I buy at a hobby shop.
