Epoxy for old bolt hole

I've got a bolt that needs to be removed and patched. The original hole can't be reused, as it's in a spot that's not optimal. Is there a specific type of epoxy that needs to be used, or will just about any hardware store epoxy putty do the job (so long as it's applicable to concrete)? I've seen the MP School of Rock page on it, but those brands look like overkill for this application. Thanks in advance.

Any concrete putty will do. Just make sure to use some rock dust/sand over the top so it blends in

Agree that regular putty works well. I've done most of my rebolting on granite crags. To camouflage the old hole, I usually take small granite pebbles and crush them gently on the epoxy with a hammer.
Camouflages the epoxy and the hole very well. YMMV depending on the type of rock.

Thanks guys. And yes, familiar with the dirt/grit approach.
