Re: RG570 edge trem post body crack
option 3 is the one I would take.
I would use a SMALL flat blade screwdriver to scrape away as little finish as possible to expose the crack. Lay the body in a position that will allow gravity to help wick the CA in. After it's dry, a little fingernail polish over the repair will have it looking fine.
On a side note, it looks like some of the knurling from the anchor has been destroyed. I would double check that the anchor doesn't have any play to it when installed.
