So lets say the sides of my AK aren't very even and there are also pinholes that need filling. Could I skim the sides of it with some JB weld, sand and paint and expect it to hold up? Or is there some other product I should be looking for?

Looks like some good shit there... I'll have to hit up Robert's Oxygen near my house and see what they have... I need to fill Paige's dad's Oxy acetylene tanks anyway.

how hard is that stuff to sand?

Saw this mentioned in another thread, anyone tried it?

DuraFill?

Cant follow the link from work. "This site is blocked. Content:Weapons"
Weapons, WTF this is a DoD network :shaking::shaking:

Anyway I have used durafill and it works great on pinholes and grinder marks.

Yes Durafil. Do you sandblast, then apply it or apply then blast? I'll probably be using a fairly soft media as 90% of my 9mm AK is already bare metal that just needs a tooth for the duracoat to stick to.

I picked up some lab metal and solvent today... $40 for the small containers, which would still be enough to do 100 of the job I need to do LOL, so if anyone in my area needs to use it for something, let me know and I'll share LOL

I figured the solvent might be good to thin it out and try and smush it in the pinholes a little better, plus it should go on a little bit smoother I'm thinking...I need to pick up a putty knife still though, somehow in all the tools I own, a putty knife is NOT included LOL

SB first.
Apply the Durafil to bare metal or park.
You can build up coats like doing sanding primer on a vehicle. Smooth with 220 between coats
