My suggestion for painters tape is for large coverage. If you need a fine edge, put the Tamiya tape down, and then backfill behind it w/ the Painters Tape. That way you arent wasting the Tamiya tape.

That's odd, the Shurtape I have has much better adhesive than the blue painter's tape that I use for more general use (like inside the body to mask inside the glass to keep overspray at a minimum). Mine has the same kind of adhesion as Tamiya tape. Not to mention the tape is far smoother than regular painters or masking tape.

Once I have an edge sealed, I then use Glad Press 'n Seal as a general mask for large coverage. It's great, it has just enough stick to work as a perfect general mask w/o having any real adhesive to mess up paint. It'll only screw up paint underneath if the paint isn't cured completely (same for any masking materials).

Hmm, wonder if maybe I got a bad roll or something.

The couple times Ive tried using it, it just never stuck very well, either to itself or to the painted plastic it was applied to.

Are you using the Shurtape Gold, or just one of their more standard tapes? It's the Gold line that's just like Tamiya. They sell other more mainstream painters & masking tapes. Lowes carries Shurtape products, but not the Shurtape Gold. The Gold is sold to people doing intricate masking for detail painting around the house, for the same reasons it works for us on models.

Just to reiterate;
chances are, the reaction you experienced isn't because of the type or brand of tape you used.
It is more likely due to paint that has not cured properly being sealed in by the tape.

Tamiya tape does not leave residue. But it will react with paint or clear coat that's not cured, so I generally let paint cure at least three days before I put masking tape on it.

Not all blue tape is the same. I've gotten excellent results - similar to Tamiya - from 3M Scotch tape for Delicate Surfaces. It's got good adhesion but doesn't lift the paint.

I love Press n' Seal, by the way. It's a great time and labor saver.

Ok I will be fine then, I always leave my paint to cure for about 4-5 days.

To be clear; it isn't a reaction between tape and paint.
It is an effect caused by solvents in un-cured paint being trapped and unable to escape evenly and/or properly so yes, leaving paint to cure will prevent it occuring.

Thanks for the inputs guys!

Was rushing the coat thats why it got crazy now im sure of it, thanks!

Did anybody already use the Frog Tape?

[Didymus]

More clarification: With regard to curing time, I was referring to synthetic lacquers like Tamiya TS-Series. Enamels need quite a bit more; I dunno about acrylics.

I do know that surface prep is especially crucial with enamels. Donn Yost is the "go-to-guy" on that subject.

According to their website, Frog Tape's new "PaintBlock" technology works just with latex paint chemistry. Doesn't sound like it would be applicable to the kinds of paints we use.

Great idea, though! (There are other ways to prevent seepage, but that's a subject for another thread.)
