Many of us have had this problem at least once. Burnish the label on to the blank completely. Color preserver around the edges will help, as does Hard as Nails. Be careful with the alcohol as it can work against the adhesive and cause the edges to lift, so let it completely dry before applying the label (if you can smell it, it's not completely evaporated). Wipe it down with a clean cloth and then lift any remaining lint off the blank with blue painter's tape, then apply the label. I think the final finish generates too much heat when applied thick, so I apply several thin coats (cure between coats). I routinely use ProKote over labels without issues so long as I clean the blank and remove any trace of the alcohol and then use color preserver or Hard as Nails on the edges. I have tried U40 PG and don't like it on labels much, at least not by itself and usually put ProKote over it. Might as well just stick with the two part stuff all the way through. I know how it is...you apply ProKote and think you're good to go, but then a few hours later you notice it's lifted. Try one of these techniques, keep an eye on it and if it lifts, pull it off and clean up the uncured finish with alcohol. No big deal. ProKote is pretty forgiving for the first few hours.
