Original fine heat: 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 will not create any extra space between the pieces.//SUPER T MEDIUM: viscosity (200-300 cps) similar to syrup, perfect for gluing materials and somewhat porous parts that have small gaps between them. It dries at a slower speed (10-25 seconds) than Hot Stuff. It can join wood, metal, rubber, nitrile, compounds such as carbon fiber and Kevlar, many types of plastics, and more//SPECIAL T THICK: viscosity (1150-1500) similar to honey. The special T works great when used to join porous and non-porous parts together, and can fill larger spaces than our average CA Super T glue. It is best used for parts that are missing or that don't fit together very well. You can join the same materials as with our other CA glues: wood, metal rubber, nitrile, composites, many types of plastics- and the special T is effective even when a poor fit makes the parts seem impossible to adhesive//Professional tips from HOT STUFF: slide over the nozzle to allow an even more precise application of glues than nozzles those that come with the bottle. Apply your instant glue with more precision than ever, saving glue and cleaning time. Pro tips have the same diameter from base to tip. If it gets stuck, just cut it off, you'll still apply the glue just as precisely! //
