Thinning Tamiya Smoke

[Radarman]

I'm about to try post shading the undersides of a 1/48 scale Albatros D.V. It is painted Light Blue and I would like to help the ribs show a bit.
My plan is to post shade with Tamiya Smoke. I've masked the ribs with thin strips of tape. What would be the best thing to thin the Smoke so
as not to over do the look? Any ideas will be appreciated.

                                    Thanks, Kevin

I use Mr Color thinner for all Tamiya and Gunze paints,works just as well on the acrylics.I would thin it down to a wash and take it easy to avoid overdoing the effect,you can always add more.
