In case any of you were interested in repainting your models, there's one simple trick to doing it (as all the raven guard were x-ultra marines of mine). The trick is... Simple Green. It does work as well as everyone says it does. I did about a 80% solution:20% water ratio, and let the model soak in it for about 3 hours (the longer the better, 3 hours is really the min unless you want to do multiple cycles, which I did). I found that GW paints come off with ease, just grab a tooth brush and scrub away (with the exception of sunburst yellow). As for P3 paints, they take a little more scrubbing and time (in particular, their white - took 2-3 cycles with a good day soak)... The great part is, after they are cleaned, the base coat persist. I just took the cleaned up models, gave them a new thin basecoat, and they were good to go.
