I've always used Microscale Micro flat to put a matte finish on my models. I've applied the finish using diluted micro flat and an air brush. I've never had any problems with 1/72 scale models but have notice inconsistent results with 1/144 planes and small ships and tanks. I'm probably too much of a perfectionist but sometimes it almost looks a bit glossy and other times I'm seeing a some haze.
I'm curious to know what people are using on their repaints and shapeways models and any good tips on products or techniques.
Thanks in advance,
