interesting. thanks for letting me know. i have the blackened slide. im also considering duracoating my benelli, but now that my understanding of the coating durability has changed, i doubt ill touch either of them. do u have any pics of the guns/wear?I have a few firearms that are Duracoated. A couple Of Ak's and one of my AR's and my Remington 870 will hopefully be done soon. You didn't say if you had the stainless or blackened slide but if you are looking to protect the slide because you are worrying about the finish wearing off, I think the duracoat will wear off long before the finish on the FNP will. If you just want to change the color in general then go for it. But on my AR where the high wear areas are like the mag well the duracoat is starting to wear off from mag changes. So to coat it to protect it you may not get the results you want, especially if you plan on carrying it. But, to each his own.
