Hot Stuff is our thinnest glue with viscosity similar to water and no surface tension. When you have parts that fit exactly together, get them in position, run this glue along the crack, and it will wick right in. Curing time is five seconds between tightly fitting, non-porous parts. We recommend using the NCF Quick accelerator to ensure a complete cure of the bond. Store unopened bottles in the freezer to extend shelf life. Bottles which have been opened will experience a shorter shelf life if put into cold storage.
