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 - Spotcheck Solvent Removable Penetrant, 16 oz Aerosol Can | 01-5155-79
This post emulsifiable/solvent removable red color contrast penetrant exhibits outstanding penetrating characteristics, providing maximum reliability in locating surface-open flaws and discontinuities for a variety of applications, such as welds, forgings, pressure vessels, castings, general metal work, leak testing and power plant construction. SKL-SP2 can be used over the entire spectrum of industrial applications, where a visible penetrant inspection system meets the requirements for surface-open flaw detection. SKL-SP2 has also been successfully used on non-porous ceramics and similar materials. PLEASE NOTE: SKL-SP2 is not recommended for the inspection of plastic materials, as it may stain, soften or even dissolve the base material under test.
