Paint peeling off with masking tape.

Which tape is best?

[Consumer Reports] tested six versions and compared them with plain old masking taping tape.

FrogTape Delicate Surface tape, around $6 to $8, was the clear winner. It left a very sharp line, was easy to remove, and didn't damage any surface no matter how long was left on. […] [CR] painted a blue topcoat and let some surfaces dry for half an hour, others for 4 hours, 24 hours, three days, and 14 days before we pulled off the tape. […] None of the tapes damaged any surfaces or left adhesive residue, but they were slightly harder to pull off. Masking tape tore when peeled, creating more work.

Again, what DoogATX said, detack that tape a whole lot.  I've masked over Vallejo acrylics after only a few hours with no issue.  I don't really press the tape down hard, I let it rest on top and mask.  With this method, you have to spray at 90 degrees to the surface, and I get minimal overspray if any.  The other trick is when you peel your tape, peel at a 45 degree angle and in a fluid motion.  Priming first always helps too, as hypertex mentioned.  

ok what everybody else said plus do not use paper type masking tape I learned my lesson on that years ago I switched to blue painters tape Second do not mask directley over Acrylics seal with a gloss coat first let dry at least 24 hours. Paint then when you remove mask pull the tape back over it's self at a very sharp angle. Along with what everyone else said this should solve your probluem.      ACESES5        

Basically what Chris said. Acrylics don't have the same "bite" as enamels or lacquers, and tend to adhere better to themselves than to underlying paint or plastic. 

I would get some Tamiya tape and de-tack the stuffing out of it. The heel of your palm and underside of your wrist actually work a little better than the back of your hand for de-tacking. Don't know why but that's what I've found. I would do more than take a bit of tack off...de-tack as far as you dare.

What brand acrylics are you using? Some brands are just notorious for this and should be tossed imo.

Acrylics have that tendency. There are several things you can do to help.

1. Make sure you allow time for the paint to fully cure.

2. Use a low-tack masking tape, such as Tamiya masking tape.

3. Stick the tape to the back of your hand before you apply it to your model. This reduces the tackiness a bit.

4. Using a primer coat can also help paint adhesion.

Hope this helps.
