Enkay140-B Extra Fine All-Purpose Blue Polishing Compound (1LB)

all good

Love the blue 🔵 nice finish and less debris like the green one . Good for ultra fine surface

In current year 2017, this stuff is coming in at a price point well below $1/ounce, for almost the same price I paid in April 2014. I see a lot of complaints here about how this "blue rouge" (heh) compound is very dry, crumbly, and more difficult to work with than actual jeweler's rouge. I'm in full agreement with those dissenters about those particular characteristics of this compound; however, one might wonder how that distinguishes this compound from Enkay's own greasy jeweler's rouge and green stainless steel polishing compounds (as well as woodstock and a couple of others). Perhaps the fact that it is so dry, hard, brittle, and crumbly might provide some insight into how this compound is different.This extra fine blue compound was primarily designed for polishing hard plastics, which is not quite evident from the description, but something I arrived at after some web searching and investigation.To apply this to a buffing wheel, you essentially have to spin the wheel fast and press hard enough to generate the friction to melt it or preheat/slightly melt it before applying it to the wheel. It's definitely much harder to apply than the other sticks I have, but it's worth it.This compound will bring out a very high polish like real jeweler's rouge, but it works well on plastics and even fairly hard stainless steels.That brings me to the main reason I bought this stick, a little over 3 years ago: an inexpensive, extremely fine, polishing compound I could apply to a side of my Stropman 4 stroke strop to finish polishing knives. I have to push down hard and rub vigorously to get this stuff applied to my leather strop. A note of caution regarding knife sharpening: some steels, like S30V, is that seem not to enjoy that much of a polish (this will polish that as well, but at that level of polish S30V feels duller). This compound works very well on most of my stainless steel knives and results in a polish that exceeds Spyderco ultra fine ceramic stones and micromesh 12,000 belts. This compound really excels on VG-10, Elmax, Sandvik, and other stainless steels that benefit from a very high polish on the edge.p.s. I can also suggest powdering this compound and applying it to a microfiber cloth for various polishing tasks.

I do a bit of polishing on firearm parts as a hobby. This was a good quality product at one of the best prices with my delivery needs factored in, at that time. It was well packaged for product protection.

This should last for ever. Using for polishing resin work.

As some have already noted, this product is hard and dry. I thought the other reviewers likely received "old", dry stock. I hoped I would receive a "fresh" bar with a consistency of Dove soap and be able to easily apply it to a 5" diameter wool-felt ("hook and loop") buffing pad. That proved not to be the case.Spinning the buffing pad against the bar just generated blue dust, with little or no blue compound adhering to the buffing pad itself. Other than abrasive powder, this bar likely contains a hard hydrocarbon-based wax filler. It can be melted in a metal can over a low gas flame, but when removed from the heat, soon solidifies again. It does not seem to dissolve in alcohols or ketones (I tried isopropyl alcohol and acetone).My workaround was to shave small pieces off the blue bar using a sharp knife into a small container (a plastic measuring cup from a bottle of liquid laundry detergent), add a small amount of Mineral Spirits (i.e. hydrocarbon distillates), then crush and stir the pieces into a smooth paste with a metal spoon. After that, it worked as desired, on the wool-felt buffing pad, to polish a cultured marble counter top.Also, I hope these pictures, from an actual Enkay bar package, help those of us unfamiliar with the various grades (coarse to fine) of Enkay polishing compounds choose the requisite grade. The final picture shows my use of Enkay blue paste, after blending with Mineral Spirits.
