Hot Stuff Original is Satellite City's fine CA glue with a viscosity (3 cps) similar to water and without surface tension. When you have parts that fit exactly together, first put them in position, then apply this instant glue along the crack, and it gets right inside. If you have tight joints made of non-porous material, Hot Stuff Thin will give you the best results, since it won't create additional space between the pieces, and since you get the parts aligned before applying this instant glue, you can be sure that they'll be perfectly in place when the glue cures. Hot Stuff Original is also ideal for filling and stopping the spread of cracks and hair lines on furniture, cannons, wood that is turned on a lathe (such as in white pen) and stone. To strengthen stone and porous wood, apply Hot Stuff to the entire surface and let it soak into pores and cracks. You can also use this instant glue on carbon fiber or fiberglass fabric instead of using resin. Hot Stuff CA glue will harden other types of fabric as well - in fact, professional dancers at the best ballet companies use Hot Stuff to strengthen the material of their pointe shoes. The drying time is three to five seconds between tight and non-porous parts. We recommend using the NCF fast accelerator to ensure complete healing of the joint. Store unopened bottles in the freezer to prolong shelf life. Bottles that have been opened will experience a shorter lifespan if they are continuously removed and put back into cold storage. The Pro tips slide over the nozzle to allow an even more precise application of our glues than the nozzles that come with the bottle. A Pro tip has the same diameter from base to tip, so if it gets stuck and you have to cut it, it will continue to apply the glue in the same way as with precision. Each box comes with 12 professional tips.
