Hot Stuff Original is Satellite City's fine CA glue with a viscosity (3 cps) similar to water and no surface tension. When you have parts that fit exactly together, first put them in position, then apply this instant glue along the crack, and get right inside. If you have tight joints of non-porous material, Hot Stuff thin will give you the best results, as it won't create extra space between the pieces, and since you get the parts lined up before applying this hot glue, you can be sure they'll be perfectly in place. its place when the glue cures. Hot Stuff Original is also great for filling in and stopping the spread of cracks and hairlines in furniture, barrels, wood that is fired on a lathe (such as pen blanks), and stone. To strengthen stone and porous wood, apply Hot Stuff to the entire surface and allow it to soak into the pores and crevices. You can also use this instant glue on carbon fiber or fiberglass cloth instead of using resin. Hot Stuff CA glue will stiffen other types of fabric as well - in fact, professional dancers in the best ballet companies use Hot Stuff to strengthen the material of their pointe shoes. Dry time is three to five seconds between tight and non-porous parts. We recommend using NCF Rapid Accelerator to ensure complete bond cure. Store unopened bottles in the freezer to extend shelf life. Bottles that have been opened will experience a shorter shelf life if they are continually taken out and put back into cold storage. The Pro Tips slide over the nozzle to allow for even more precise application of our glues than the nozzles that come with the bottle. A Pro Tip is the same diameter from its base to the tip, so if it gets stuck and you have to cut it, it will still apply the glue just as accurately. Each box comes with 12 professional tips.
