Brass shower valve body has gouges, what can I do to fix?

[House Flipper]

have a Moen shower body that leaks. the previous idiot to remove the cartridge gouged the inside of the valve body. now with a new cartridge, new o rings, it leaks worse than the old one. Worst case scenario is to replace the shower valve body in the Tiled shower.
Has anyone successfully used JB Weld or similar product to "smooth" out the interior of the body and stop the leaking? OR perhaps a sealer product around the cartridge. I tried plumbers grease but it's not "stiff" enough. any secret plumber fixes?
Thanks for any advice
Michael

Thanks for the reply. Thats what Im afraid of. I have nothing to loose trying a JB weld fix, but I was hoping for a pro plumber "secret" solution. Hahaha

I have not seen it obviously and the first thought was as per @king of pipes. I am 99% sure that's the only option.

Is this brass without chrome? just a body that has been removed from the wall?
Any photo's?
I had an idea fly through my vivid imagination but I'd need to see it to say if it might work.

Post a picture of the shower it may not be as bad as you think to swap

the body is still in the wall, I'm trying to avoid tearing the tiled wall out. it is brass. I do have a new one that is the same as in the wall, so at least that's a positive. I don't have pics of the body in the wall or to show the gouges.

No it won't work.
You need to change the valve.
As KOP said, it won't be that difficult.

Do you have a spare tile ? If not it shouldn't be to hard to match one up plenty of Travitine available , grind out the grout line then chip away at the tile till removed they are pretty soft so shouldn't be to difficult you then have access to the valve body kop
