Is this normal black polycoat finishing or finishing defect? It is uneven throughout the frame. Just curious.

I'd say that's fairly normal. However, are you certain that is not oil residue?

I am certain that it is not oil residue.
That's what I thought at first, then I wiped it down, still looked like that.

Did you wipe it down with something like isopropyl alcohol or did you just wipe it down?

Wipe it down with an oily rag and see how it looks after that.

I wiped it down with an oily rag first, then wiped off the excess with a lint-free microfiber cloth.
I did not use any isopropyl or solvent solution.

You might try using isopropyl alcohol or something to actually remove most of the oil. Pores in surfaces like polycoat (and many other types of finishes) can be weird about how they retain oil. It looks like retained oil to me in the picture. But that's just a picture and it's hard to tell. Wouldn't surprise me much if that's what the polycoat looks like. It's a pretty utilitarian finish (and it's good for that), not always 100% uniform.

It seems (I could be wrong) that a painted/dipped surface coating wouldn't need oil to protect the finish/metal like bluing or parkerizing does.
But I still wipe mine down with an oily cloth (yeah, a rag) when ever I clean it or put it away in the box for some reason. And, on some guns, holster wear has worn completely through the polycoat showing bare metal and that will rust if not oiled/wiped.
I don't really recall a finish looking spotty after wiping it down with that oily cloth, but I don't wipe off the excess either. I just wipe it down good and put it away.

Thank you gents for the heads up. I will try the isopropyl alchohol and report back. I just picked it up from the LGS last week.

Thanks alp3367 for your insights on the polycoat and how they retain oil. I cleaned the area with isopropyl alcohol and removed the factory oil. Now the finish looks even and smooth :)

Interesting. I never noticed blotches on mine after oil rag wipe downs.
My bad eyes probably!

I always give mine a wipe down with an oily rag as a matter of normal cleaning and none of them show any such blotches. Must be a rough spot in the Polycote that holds more oil in that section. I Know they have inconsistencies in the Polycote sometimes. One of my compacts has a very thin finish in comparison to some of my other CZ's. This is nothing more than epoxy paint so there's that.

Good results!

My pleasure, happy to help. As an aside I've handled hundreds of handguns with many different types of finishes and this phenomenon is common to just about all of them.

Last thing I care about is the finish. It's going to get holster wear soon enough.

Can isopropyl be used on a satin nickel finish? Or will it hurt the finish?
