PW: <Angelic_halo on> I am so sorry to hear you are disappointed with the unit. I will gladly give them a good home so you don't need to see them any more. <Angelic_halo off/>
Joking aside, that unit looks rather awesome to me. I like the mid-yellow mixed with the darker color. The banner is absolutely fabulous.
As for sealing miniatures, I used Krylon gloss varnish (now with extra shine!) for protection, and use Polly S Figure Flat for the matt finish, although I prefer Testor's Dullcoat. I've been experimenting with going back with some of GW's brush-on high gloss finish to hit areas that I want shiny on purpose, like metals. I left most of my Daemons shiny, because it makes for a 'wet' look that I wanted. After all, slimy Daemons are scarier than Daemons with good hygiene.
