Heard about Boelube for years. Finally had a chance to try it on several projects. It definitely works well and better than anything else I have ever tried. Would recommend.
Got it for AR assembly and it is the cheapest way to get it.

Magnaflux - Penetrant Inspection Kit | SK-816
Spotcheck® products are the most reliable and widely used penetrant inspection method that reveals cracks and other surface discontinuities in virtually any non-porous material.
Spotcheck®'s formulation, using a high concentration of quality dyes, together with high quality solvents, provides the best possible dye penetrants for finding defects. Other products may skimp on dyes or use inferior solvents that cut costs. In doing so, indications do not appear as bright or vibrant and cracks can be missed. Some inferior solvents may also cause health hazards. Our developer’s even spray pattern provides a uniform coating. Our Spotcheck® products are the most widely used across the globe.
The SK-416 Portable Kit includes everything needed to perform visible red dye liquid penetrant inspections. No ultraviolet black light is required for inspection. The kit comes in a portable plastic carrying case for easy transport to remote field locations.
