getting rid of decal shimmer

Dave I don't know if this will help but I put a coat of pledge One coat floor polish on that I dilute with water and then add some dull coat to this and air brush it on before I weather the Build this tends to get rid of the shine I also use this coat on around the site of the decals I find this helps to hold the decals on better too.Pledge floor polish is "future in oz"

Here's what I do Dave.

Apply a gloss coat (I use Future), and allow it to dry.
Apply the decals using both decal set and decal sol solutions.
Apply 1 to 3 coats of dullcote.
Weather to my hearts content. (and I use a lot of pastels too)

Yes first after the paint is dry and you are ready to do decals spray a gloss coat over the whole kit make sure it is glossy I use testors high gloss for model cars or what I did with my King Tiger and t-34 was if you have an airbrush just spray where the decals are going to be. I Never used the future method but I know some guys here do but it is basicly the same process.then after you have achieved the show room shine place you decals as shermanfreak stated using decal set, I use a product called solveset (I highly recomend)it is great. then let dry over night and then wheather followed by flat coat.and if you want wheather again.

I use Testor's glosscoat first; let it dry overnight then decal with Micro set. After the decals dry I put another gloss coat down and let it dry. I put my wash on then if I'm going to use one. I let the wash dry a couple of days then hit it with a couple of coats of Testor's dullcoat. I dry brush or graphite last. That's just my way of doing it.
