Actually no, as the current most used RAM in the world the iron ball paint absorber requires it to be applied evenly for it to work best, in a progressively thicker layer towards where the radar is most expected to come from, no it bumps here and there. So the correct application would see the paint being thickest at the nose and then continuing along the whole length of the plane. And without proper treatment it degrade leaving us with F-22s looking like this
See that, that is RAM applied on non edges. Only a small part of that is actually some sort of hinge or door to get to the camera thing. The rest is smooth.

Check the wing edge cross section above.

The metallic, plain surface works as a waveguide.

You found this under the skin:
fetch


Rivets, screws, joints and so on.
Each of them increase the radar cross section.

For 42min the missiles are too far away for me to get a clear view off, and at 19.20 the missile looks more like a novator with some sort of rocket booster at the end. A very similar missile but a abandoned project as far as I know off.

19:20min was inaccurate on my part, I've edited the post in the meantime to say 19:17min:

Those are pretty clearly R-37Ms. Better view of aircraft mounted missiles from 21:52min on. I'll leave it as an exercise to the reader to compare to the R-33 which also feature in that video.

If that is a wave guide, then it is the least looking wave guide on earth. Even more telling is that there is no evidence of the F-22 having waveguides, and even if it has what is it use for ?
Waveguides look like this

Not some metallic skin across the aircraft.

No problem, but again the missile in question could very well be the R-33, the predecessor of the so called R-37. A good reason for this is that not only the missile was look very much like the proposed R-37M but it was in service for some years before the USSR dissolution. And it was also used by the Mig-33, but it was never further developed.
EDIT : I also looked through part 21.50 but the problem is the R-33 shares the exact same dimensions and wing design as the proposed R-37 and they are also hung from the same positions. So unless the guy is helpful enough to show us the description on the missile, it did be impossible to discern which missile is which.

As this website picture shows, the coloration and cover cap of the R-33 depicted is the exact same coloration as the one in the video.

Sigh... no, it can't. The R-33 has MUCH larger strakes and tail fins, see 25:09min for example. As for the red cap, that's just a protective cover for the seeker radome - they're always red on Russian missiles. Most prominently, on the R-33 there is virtually no gap between the fins and strakes, while on the R-37 the latter end well forward of the fins.

That is hardly a deciding factor:

If we see a purported picture of the R-33S the last know improvement of the R-33, the the strakes and most importantly the tail fins have been redesigned to be smaller that the R-33, which fits the description.

Not some metallic skin across the aircraft.

Waveguide works as a fiber optics for longer wavelength.

How much energy the fibreoptic reflecting BACK to the laser ?

How much energy a non normal incidence laser reflected back from a mirror to the emitting source ?


So, the non-normal incidence angle from the skin of the aircraft will reflect back the to radar as much energy as a waveguide reflect back to the source.


The reason why there is RAM can be found in equation 6.40 / 6.41 / 6.42

Backscattering in the specular direction occurs only in the case of normal incidence, ϑ = 0; in this case, results are polarization independent;
