Does bead blast and blue finish make it more prone to rust?

I'm consideriing re-finishing ideas for a camping gun and wondering if a high gloss blued finish has more corrosion resistsance than a bead blasted and blued finish.

I am thinking the rougher open pores would make the bead blasted finish more susceptable to rust.

Also, when a gun is parkerized is it generally bead blasted first?

Blued finish of any sort is a lousy rust preventative, it's more for apperance. You don't have to blast before parking, but it doesn't hurt, think it will speed the process up as well. Parking would be a much better finish for a bush gun.

Bead blasting (glass beads BT10-BT8 media) tends to mini peen the surface, and gives a satin type finish. There are no open pores. Now sand blasting with sharp edged media will really roughen up the finish, and make "open pores".

Beading shouldn't be any more susceptable to rust than gloss blue.

Not true

Not true

I'm not saying it has no protective qualities, but blueing is itself a rusting process, and it isn't anywhere near as corrosion resistant as almost any other option short of bare metal. Done right though, nothing else is near as pretty!

Yes it does require more care in cleaning , any smooth surface is a tough surface.

Although blueying is a corrossive process there are different types of blueying for instance the rust blueying process has excellent rust protecting properties, probably the best rust protection next to plating the metal. The more surface area you expose to moisture the quicker it can rust because it traps moisture, it can also be used advantageously, if you wax the metal it will create a very good rust barrier because all those little crevices hold the wax better.

I hear what your saying, and rust blue is the best of them (cold blue is strictly for apperance, no protection qualities whatsoever). But if you Parkerize and rub a good waterproof grease into it, man it's indestructible. And I'll take a good epoxy coat like gun-tuff or arama-coat over even rust blue if its applied properly. ditto hard chrome or electroless nickel like NP3.
