Smoothing out rough surface

[DoctorLove]

Hello guys. I recently acquired a used vz2008. The previous owner drilled 2 holes on the left side of the receiver and then changed his mind and filled the holes up with what seems to be jb weld. It's blotchy and uneven. Then he repainted the receiver black. Whats the best way to bring the receiver back to a presentable conditon? Weld the holes and the mill it flat? Maybe sand the jb weld flat and cerakote?
And is there anyone who does this kind of work professionally for a reasonable price?

Maybe post a pic? Depending on how bad the holes are, you may be able to get away with sanding, blasting the entire receiver to get a uniform finish and then cerakote it.

Place sandpaper on a piece of glass or marble.
Put water on sandpaper.
Put part to be sanded flat on water and work the part back and forth until the part is flat.

The uneven surface isnt the outermost layer. Its like havjng to smooth out the lightening cut on a milled ak receiver. I guess it would be easier to explain with pics. Ill try the opposite of that method by attaching sand paper to a piece of flat wood

Ok here's what i've done in the past.

clean the affected area, clamp a aluminum backing plate inside the receiver, weld up the holes, I then use a right angle die grinder with a 1.5" sanding disk to grind down the weld flush, then you prep and paint, coat, or parkerize.

and yes i can do it, and yes for a reasonable cost. but you will need to remain on site while the work is being performed.

PM me an we'll talk.

Is there a reason you use an aluminum backing plate instead of copper?

Because I don't have any copper plate. If I did I'd use it. But I've always got a piece of aluminum laying around

Sandblast ALL the epoxy out of there before you think about doing ANY welding.

You'll find out. Ever try to weld over a dirty painted or otherwise screwed up surface?

Bad welds.
