Thanks for finding that. Though the J20 one seems to be able to undergo less cycles?
Also that tape is not temporary. It is used during flight, like the pic Deino showed.

F-35 does not even bother to cover it in anyway, just leaves a gap.One must scrutinize the actuator housing for the J-20. Compare it with the F-22 and the F-35. I smell a technological deficiency for the Chinese team here.
I'm attaching an F-22 integrated actuator (ailerons) here. credits to murphy,aircraftresourcecenter.com
The way J20 does is exactly the same as F-22. If the material are the same, the life cycle should be in the same range.
I think that tape is still there on that F35?, i guess it just doesn't cover the gap when actuated too far
It looks like the tape only has adhesive on half of it and is rather stiff.
By tape in my post of F-22, I meant that it is temporary, it is not a integral part of the aircraft, probably being there for storage or maintenance purpose. What you refereed as "tape" are the edges that are thicker than the surrounding surface and of different shade. They are not tapes but integral part of the aircraft. The difference between J20/F22 and F35 is that the edges of the actuator housings of the later are rigid rather than flexible, the former will cover the interior of actuators in all situations while the later will expose at big angle (too far), after all F35 was not designed to be extreme in stealth as the former due to its mission purpose.
It was quite the relief. However,The F-22s does not seem to have the "slits" as pronounced as the J-20. Maybe I'm nitpicking. But so do radars. Thanks for that image.
It is just the light condition of different angle of view. Their looking "pronounced" on J-20 is only because they look darker and longer when viewed straight below at 90 degrees. F-22 looks less "pronounced" because the photos were taken from almost 0 degrees from behind, that also makes them shorter than they really are therefor less "pronounced".
The only thing matters regarding these slits are their lengths and widths of their gaps. The factors determine their reflective-ness and deflective-ness to incoming radar waves. And these dimensions are the same in both F22 and J20 after our brain make the perspective correction of the different photos.
