How I use E6000 is I make sure that I have my "Clamps, Tape, magnets, paper, etc..." all ready, I use a utility knife to lightly score the side that I put the glue on. Let it sit for 5 - ten min. depending on air temp. Put the pieces together. Use the "Clamps, Tape, Magnets,etc..." and let it set. I like to use the glue in the evening. The reason why, so it can sit overnight. By the time I get home frorm work and having dinner, "24 Hours" has passed and then I can remove the "Clamps, Tape Magnets, etc...". Also I like to let the part that I am working on air out fo a few days. A good tip for working with E6000, use it outside and use a resperator an not a dust mask! The Fumes are Tough!
