Yes... you apply the decal the same way you otherwise would, when you get it on initially and it dries and sets, you apply the vinegar to it, make sure not to touch it once the vinegar is on... you may be tempted to as it may look like it is shriveling up- this is ok, as it dries it will settle into the nooks-and-crannies and look much better! Tough decals may take more than one application, just make sutre it is dry before applying again!
