Shotgun Refurb: Need Coatings Prep Advice.

[Higgy]

There's an old Stevens side-by-side 12 gauge at the local shop. Its going for cheap money. I'm probably going to go get it tomorrow, and add yet another distraction to my already distracted life. The gun is probably '60s vintage, from the looks of it. Double triggers. Huge dent in the left barrel right at 19" so I am considering doing a chop job on it, and turn it into a coach-gun. The gun is very pitted, hence the cheap price. The pitting is what I want to ask you guys about.

Now, I have rebuilt 11 handguns, and easily twice that many long guns. So far, in addition to parkerizing and bluing, I have used KG Gun Kote, and Duracote, with great results. The one thing I have not been too concerned with is pitting. Most of the guns I am getting to rebuild and play with are "rescues," meaning they are in pretty sad shape. Rusted, busted old junk, reworked and made serviceable again. Its a darn-good feeling, actually! SO anyway!

Finally getting to the point - is there a method - other than stock removal - to fill in the pitting and use a bake-on coating?

Lauer Duracoat sells a special filler product.
Of course, this can only be used with a coating type of finish because bluing and other chemical finishes won't color it.

When baking be very careful about the heat. These old guns barrels and ribs were soft soldered together with an almost pure lead solder that melts at lower temps.

Hmmm... I might have to look into that. Thanks!

Bead blast the pits ( or etch them with any of the rust removers, rinse well...then rinse again!) I use the two part Duracoat with great results, the spray/bake Duracoat works well too.

Andy! How's that XD45 working? Still got it? I passed off that Kimber to my son.

I'm going to be taking on a similar project soon, but with a Stevens 520 pump. I'm going to use Brownells alumihyde II. Has anyone tried using jb weld to fill pits before painting?

I've used JB Weld under Duracote to fill in checkering on a stock I did once. It came out real good. I sandblasted the stock and soaked it in acetone for a week to leach-out all of the oils.

I used to be a printing machinery mechanic. I used this titanium putty: http://www.devcon.com/products/products.cfm?market=Maintenance & Repair&family=Titanium Putty to repair a big divot in an impression cylinder that the chucklehead operator ran an allen wrench through. It made a nice impression of the allen wrench right in the spot where the numbers are supposed to land which number your checks. Well, long story short, it did a fantasic job. This stuff sets of hard and is very durable. Again, I would be sure to blast with 120 grit AO before applying. Oh, and another word of advice... definitely try to be sparingly when you apply it, because this stuff does NOT want to sand down very well at all. Body filler it is not, so better to need a skim coat after than to apply too much in the beginning.
