Benefits: This product is packaged in the preferred aerosol manner for ease of use by machinists. Formulated to provide a very thin coating on the substrate to be matched, for ease of high spot identification and clean up. Using this product will significantly reduce the amount of time required to ensure that bearings, shafts and housings do not have points of interference which will reduce heat and wear resulting in a longer life of the component.

I was expecting this to be a little more concentrated, a bit more like Dykem.However, it worked fine and if you want a thinner coating it will work well for you.

Works well enough to get through most jobs. Nice small and affordable container for DIY'ers. It is dark, even with a light spray, and wears away cleanly. This is my first time using this type of product. It works well. It seemed like it needed a few light coatings to get the surface covered. Sometimes there were bubbles in it, and the color didn't appear very uniform. It laid down in splotches and even short squirts made puddles on my work. Drying time also seemed longer than it should be. Maybe this is normal, it's just my observation and have nothing to compare it to. I was able to successfully complete my project and I have Crown to thank for it.

I didn’t care for it. Messier I think. Doesn’t work as well

I was going to buy a tube of prussian blue for a project when I came across this product. I thought I might as well try it. I was pleasantly surprised as it sprayed a perfectly even coating unlike smearing prussian blue from the tube. It didn't get all over my hands and the only mess was having to clean the thin layer off when finished. I highly recommend this product if you need to detect high spots. I will definitely buy this again if it ever runs out that is!!
