Pinstriping issue

I have replaced plenty of decals and applied new ones on my current Nautique and past boats over the years with no issues, BUT I cannot seem to make pinstriping stick on my boat. It stays on for maybe one trip to the lake then starts peeling off. I have tried a roll that came with my boat that was a few years old and that peeled off so I ordered a new roll from CC and that peels off. What's the deal?? I'm prepping the surface by cleaning it with acetone. Should I be using something diff?? Everything else sticks fine.

i would try using rubbing alcohol. you can get it at at grocery store and its really cheep. i think it would work better then acetone. we used it for our old boat and it worked great
