Sets when you spray on the accelerant. This is the handiest item you can carry in your hunting bag. BE PREPARED. NCF is an extremely fast acting accelerator for all instant glues. "NCF" has an extraordinary on-part life. Apply to one part only. Part may be sprayed up to 8 minutes in advance of bonding. Apply SUPER''T'' in a spiral pattern to other part, assemble parts, and then hold firmly for 10 seconds.
