Wantsome,Pactra is the Acrylic brand of Testors I referred to in your other post.You may want to thin pearls or metallics to get them to spray easier.Thin a little at a time w/water or windex or similar medium.Pactra has a good selection of pearls and metallics,but if you're looking for natural colors look elsewhere.You may want to try Createx if for no other reason,to avoid the hassle.Just experiment till you find the one that works best for you.
