I've finally decided on which Space Marine Chapter to work on next. I've been a fan of the Blood Angels codex since it came out, but I'm not really a fan of the Blood Angels themselves. Additionally, I've just recently acquired an airbrush, so my options for basecoating models have recently expanded. I've decided to do a small force of Lamenters. They have a really cool back story and look absolutely stunning on the table.
This morning I basecoated an assembled rhino with ColorPlace Flat White Primer. It sells for 96 cents a can at your local Wal-Mart and works like a champ. I find pretty much any white primer will work so long as you make short bursts from about 10 inches away. Today wasn't humid, so no issues there. I sprayed the model fully from above, but not so much from below. Once finished, the model was fully white wherever the light would hit and a little darker from below where the shadows would be. I guess you would call this a basic Zenithal highlighting basecoat. Afterwards I used the airbrush to spray on a coat of GW Golden Yellow. It came out pretty well. A quick drybrush over the entire model of GW Skull White provides all the highlights I'm likely to put on a tank. I did do some masking and put a black tactical arrow on the top hatch. I'll post some pictures later when I get a little more of the detail work done.
