Just keep in mind that paint takes a few days to cure. It'll be dry to the touch in an hour, but it won't have hardened very much until a few days have passed. This is usually the reason behind paint sticking to the tape. If you're really crunched for time, 3M makes a tape called "Safe Release" that is really low tack. It's white (not the blue stuff that they make for normal paint masking), and costs about twice as much as regular masking tape. It's also kind of tricky to use, as the low tack means it tends to peel up when you try applying it to a curved piece. But, sometimes, when you're up against a deadline, it comes in handy. You're still better off letting the paint cure a few days, then using the vinyl stuff talked about earlier to get a hard line, and then covering the rest with regular or blue masking tape.
