I just take a sports cap water bottle and "spray" using that. Hard to get much definition at this time of the year though unless its very late or very early in the day. This is one from Gardoms edge two weeks ago:

I just bought an extension cable for my old flashlight.
It works pretty good.
I can hold the camera in one hand and point the flash with the outstretched other hand. I will need more practise, but it looks promising.
The only way I would agree with;
clean the stone carefull with a soft brush (broom)
and may be pour some water on it.

I don't like people placing glass marbles into cup marks to show them up. Better to take a photo with some light shining on to it. A fine water spray bottle is a very good idea, too.

NO!, please dont chalk them!
i like the idea of water but DO NOT CHALK THEM! also i don't think that it is a good idea to try to hollow them out, eg, moss removal.

Its rains every other day in Argyll that's if we lucky enough to see the sky, interesting topic with better ideas. Some sites in Argyll are 4-5 miles away from any road and carrying lighting equipment 4-5 miles is not that practically. I do like the idea with the water bottle sounds simple and affective.
The best idea I've heard is that archaeologist cover these panels of art up after their surveys, because the weather will wash them away in a matter of decades dew to erosion.

chalk which is alkaline applied to a rock is generally frowned upon because it has been scientifically shown to have a detrimental effect on the chemistry and/or acidity of the surface of the rock.
The best photos of rock art are usually when strong directional light is used this might be when the sun is low angle raking across the rock art panel, often this light is the best. Another method is to photograph at night or in low light with a torch to help show markings or use camera flash/flashes.
Another possibly more versatile option is to use a Photographic Light Reflector to direct light across the area you are interested in, depending on lighting conditions you might also need to shade your subject as well. reflecting light across or if using a torch it is best to have someone controlling the camera and someone controlling the lighting.
different lighting conditions can have a huge effect on the appearance of the rock art you are trying to record, even just time of day.

I recently bought a couple of these 72 LED lamps. Now I've got to find some carvings to try them out on.

Thank-you one and all for the responses and links. Personally I would not be able to use multiple flash units or an array of special lighting. As I take all of my photos on my mega-super 5mega pixel mobile phone! lol I think a spray bottle and trial and error with natural daylight, I have noticed that on a rainy days (and we do get a lot of those!) images show up clearer, but then the lens gets all raindrops and its hard to press the footery wee button to take the picture! Photoshop, not sure if I have that on my laptop, but, if I do I will have a wee play around with it.

Yes, artificial light seems to be the best:
