I have a Romanian kit I'm working on at the moment.  The only problem with this kit is the exterior of the barrel, gas tube and gas block look like they were sitting in water for a while.  It's odd because everything else looks pristine.  In fact when you look at the inside the barrel it's as though it was never fired.  Anyway, I've sandblasted everything and the pitting on these pieces are quite deep.  Does anyone have a  method for filling them up so that they won't show?  Brazing was on possibility I thought of.  I'm planning on using Gunkote for the final finish so any method used would have to withstand heat.
Thanks, John

In general I like gunkote much better than Duracoat, but this might be one case where the thicker coating could be better. There is also DuraFill made for just this type of situation...and it can take heat...guess you could use DuraFill then coat over that with Gunkote...
but in any event I'd look at the thicker DC for this application even though it's not my first choice in coatings generally.

That sounds like the way to go.  I hadn't thought of durafill, but that is exactly the kind of product I was looking for.  Something you can fill the holes with and sand off flush.

what about jb weld and then sand it down??

JB weld would work to fill in the pits but if you get your barrel cooking the JB weld might start crumbling and come off.  It's rated up to 500 F.

duracoat actually has a product just for this called "durafill". I just got mine a few weeks ago, but have not had the time to use it yet.

I plan on using it on a Romanian kit I'm working on. You might want to call them and ask about it.

I'll give them a call today.  Hey just a thought but If I decided to parkerize the gun before I apply gunkote wouldnt that help to fill the pitting?

Parking will not really fill the holes but I think that it would visually make them less noticable.

i would make it a shooter and not bother trying to fix it

but if you must you can spin it in a drill press and run some sand paper or a file over it

when copes had the rusty kits on sale for 69 bucks about a year ago I ordered one.....got it home and top cover was unusable and wood was stained but the only other rust was on barrel at fsb....finally had the nerve to do the pistol build that i had been wanting to do...drill press and hacksaw did away with all the rust on bbl....just trying to give another option.....

Thanks for all your replies.  Really helpful stuff.  I think Socandyman has it right.  It really is just shooter grade and probably that is how I should build it.  I sometimes get a little too tied up in the small details.  At least now I know what to use if I do want to fix it up.

Leave it original, the pitting anyway.


It adds to the history.
