Whatever tape you use, even Tamiya, be sure you "burnish" it down really good or paint may leak under it.
Also when you spray the paint try not to aim directly at that seam where the tape meets the plastic. The force of the air pressure may push the paint under the tape. Spray from above or away from the seam.
Some people apply a clear coat first directly along the seam so that the clear paint seals any leaks. If the clear coat leaks under its either not noticeable or easier to fix than a color would be.
