Some years ago I wrote an article for the German White Dwarf about the importance of the correct primer. I have always used the GW primer, mainly because all other products I tested were a major disappointment. The article was not ment to discuss the advantages of different manufacturers, but the more important question of the right color.
Today I would like to summarize what I wrote at that time, without trying to convince anybody of anything. Let's start with a picture....
Both Marine shoulder pads were painted with two or three thin layers of Regal Blue. Far more imporant than the obvious difference is the further advance of painting. My technique of using very thin layers of paint to create soft blendings works very quickly when I want to create shadows, but takes "years" to lighten up certain areas on a miniature. It is quite obvious that the left shoulder pad would drive me mad and take hours, concerning this fact. The right shoulder pad, in contrast, is already painted in the lightest tone and mainly needs shading and a bit of softing out the blendings in the light area. This way, I can save a lot of time only by taking a white primer.
