Will parkerizing solution mess up finished powder coat?

I have a PTR-91. I had a section of rail welded to the top of the receiver. I want to parkerize the rail. The PTR-91 is parked throughout and then powder coated on the exterior. I'd prefer to just go ahead and dip it as is, instead of stripping the ENTIRE gun, reparking the ENTIRE gun, and then re-powdercoating it. I've done quite a bit of video watching and reading, but have not seen anything about park solution's reaction to powder coat. I intend to do the parkerizing myself, in my garage, with Brownell's solution.

Here are some pictures of what I am working with. Bottom side milled to fit the ridge on the top of the receiver, centered, trued, leveled, clamped and rechecked, then attached with three 1/4" plug welds.

id give it a shot just dipping it. worst case is that you have to do the entire gun anyway. ive done similiar things with guns with duracoat and cerakote with no ill effects.

do you know what specific coating you have?

It may be fine, but, just parkerized the rail will look like snot. The varied hardeness and compostion of and around the welds is going to leave you with varied shades from grey to black. After all that effort you'd be better off and happier in the long run just blasting the whole thing, parkerizing, and coating it.

I know what the factory told me, which is the receiver is parkerized inside and out, and then the exterior of the gun is powder coated, meaning high temp baking to cure, probably 350*F or so.

Ya, but the rail being plug welded on means the only imperfections in the park <span style="text-decoration: underline"><span style="font-style: italic">SHOULD</span></span> be the three plug welds. I can live with that, as they will be under the scope. Park is a good base for Cera/Dura/Gunkote etc and I will probably wind up camo'ing this thing. At the very least I will find some black spray paint that matches the powder coat and paint the rail to match after parking if it isn't dark enough. Besides that, I am more worried about rust prevention than I am looks. It's probably hard to tell from the pics, but the stock metal and rear sight are parkerized, and unless you know it you can't tell from 12" away.

Anybody ever actually done this?
