I have had similar issues with the really shiny ones. I apply them wityh water only at first and use a Q-tip to get them nice and pressed down and then brush some Micro Sol over the top. If they look like they might wrinkle I wait 'til they are almost dry but still have a tiny bit of "flex" left and VERY gently roll the side of a Q-tip over the decal form the middle out.
BTW, did i forget to mention... VERY gently.
BTWII... what ya working on?
