Sealer recommendations for dark grey concrete coping stones

We have dark grey concrete coping stones on a low garden wall, didn't realise when we got them that touching them would leave you with black hands are that it would get on your clothes. We are looking for something to seal them with to stop that as well as help protect them from weathering so much and if possible give them a bit of a wet look. The company that makes them said to use any concrete sealer but the ones I've found seem to always be for garage floors and don't seem suitable. I also looked at Thompson's water seal but when I spoke Thompsons to check if it would do what we needed they said it wasn't suitable for coping at all. Any ideas on what we could use?

Many thanks
