I did use micro set before applying the decal and micro sol afterwards. I sanded with #3000 before attempting the decals….maybe not slick enough? I did manage to iron out most of the wrinkles, but these big ones just would not disappear. Anyways, the white decals laid down much nicer, but I did lay down a coat of clear first. Too bad, because the black stripes had a lot better definition than the white.?
