to help eliminate the "silvering" as it is called, decals should be applied over a gloss base. Silvering is caused by air being trapped under the decal when applied to matt or semi-matt paint. You can use gloss paint or apply glosscoat to the area where you want the decal to be. After the decal is applied to the gloss area and has set you then over spray the area with dullcoat then do your weathering. Also the use of decal setting solutions like "Solveset" will also allow the decal to "snuggle" down to the surface and also helps decals match the surface detail under the decal. But be sure to follow the directions when using these solutions and don't be tempted to press out any wrinkles that form while the solution is working this normal they will flatten out.
