Dullcote is very good, but very strong. I use the Testors ModelMasters Matte coat. and the Fantasy Vallejo paints are badass!!! great paint to work with.
One of the nice things about painting and resealing just the parts, and not a complete figure, is that you never have to worry about missing a spot, or getting excess paint on the wrong limb. Things won't get in your way.
thats pretty much what I was thinking, like painting & sealing the body first then attaching the arms/legs/head, then painting and sealing them and then a couple more coats to seal the whole thing.
also if anyone was wondering I use vallejo game color and I'm painting a wwe deluxe aggression
