Shake well before each use. Apply VC-3 a length of 1 to 1 ½ times the fastener diameter, filling threads 30-50%. Although material will be dry to touch within minutes, allow VC-3 to dry for at least 30 minutes (the longer the better), depending on part size. Fasteners are then ready for assembly or to be stored for later use.

Application:
For Thru Holes:
Apply several drops of the product onto the bolt at the nut engagement area.
For Blind Holes:

For Sealing Applications:
Apply a 360° bead of product to the leading threads of the male fitting, leaving the first thread free. Force the material into the threads to thoroughly fill the voids. For bigger threads and voids, adjust product amount accordingly and apply a 360° bead of product on the female threads also.
Assemble parts and tighten as required. Sets in approximately 10 minutes and fully cures in 24 hours.

Seems the Loctite can be applied with less care (precision?). And some differences in the working temperature, etc.
Choose your poison . . . perhaps there's a better word choice here.
