Help applying decals.
 

I'm not sure what I did wrong, I am pretty new to bike mechanics. I have "refurbished" 3 different bikes so far. I have had them professionally sandblasted and then I rattlecanned them and they have all came out pretty good. My most recent project, when I applied the gloss, the decals curled and lifted and tinted a tan color. Did I do something wrong? I had done this exact process three times previously with no problems.
