Thanks John! The key is a good solid gloss coat. When you apply the decal over a gloss finish the decal lays down smoothly and minimizes the opportunity for any air to be trapped under the decal. Trapped air is what causes the silvering. After the decal settles I lightly rub a moist Q-tip over it to squeeze out any trapped air pockets. Make sure you give your decal a good 15 minutes to settle before you do this. Next, I apply some MicroSol to "melt" the decal to the gloss surface. When everything looks good, I shoot a layer of matt finish over the entire kit.
