I also had some slight seam lines and pitting on mine, but as the pistol looks a bit beat up and weathered on the show, I didn't fuss with it.
As far as having the gun pristine before application of bluing, I simply wiped mine down with acetone about twice -- and yes, t did make the white rag I was using for this dirty -- I suppose it has something to do with the metal the gun is made of.
I then used hair dryer to heat gun and apply the BLUE WONDER finish, which I applied several times, but successive applications didn't make the pistol any darker. I then sealed with the keBLUE WONDER developer -- did not change the color. The BLUE WONDER finish was nice, but a bit on the grey side with hints of bronze...and it easily rubbed off -- especially the areas near handlke that have a lot of contact with your hand when you hold the pistol.
I then used some Rub-N-Buff paints (Antique Gold and Autumn Gold) to highlight the pistol -- used sparingly applied with tip of finger or Q-tip.
I then heard how well the Plum Brown finish worked, picked a bottle of this up from local gun shop for $9, and applied cold directly over BLUE WONDER finish. Worked like a charm. The more I applied, the darker the finish became...I believe I even worked in a little Rub-N-Buff WITH the Plum Brown -- or maybe applied a little Rub-N-Buff and immediately smeared it around with the Plum Brown solution.
I will take more pics soon, but have posted pics of how it turned out a few posts ago -- I think it looks pretty good - AND the finish appears to be more durable than the Blue Wonder alone -- although I have seen a little of it wear off near wehere grips meet pistol frame and a few other high-touch points...but I plan on touching up with more Plum Brown so this shouldn't be an issue.
I also rubbed the entire gun down lightly with a little gun oil...not sure how well this helps as it has only been on ther pistol a day or so, but I figure it can't hurt.
I am wondering if the one shot of Mal holding pistol to camera -- where it appears to have a very glossy look -- if this wasn't the result of it being freshly oiled, as the oil does give it a shiny appearance when first applied.
