    The Yanks have converted F15 to low RCS with internal bay payload. Can Russia / China do the same with older metal planes, they have or sold? How did they do it? Nano paint? Composite panels stuck to original skin? Or new replacement composite skin panels? Can you guess?  Best solution is replacement panels. Including internal coated shaped panels. Can these be made and sold to different country to change to stealthy airforce? Iranians made coating of carbon nano - tubes also to stealth in some frequency of radar. If plane radar also works in this frequency then jamming by enemy does not reveal plane either. Imagine ordinary Chinese J7 jet with stealth! With low RCS external payload.

    I think that reducing RCS on a plane is useful to a point. Beyond which we have diminishing returns. That is we get reduction to a point, but never to zero. At very high expense. So high that it affects the number of planes we can produce. As long as the plane RCS is reduced enough to make it look much smaller, then jamming and decoys provide a more cost effective way of making plane hard to hit with radar guided weapons. And that is all  we want. And we achieve it at fraction of cost.

    Older jets can be given new life in this way. Using a combination of paints and shaped composite panels in some places, together with easy replacement of some parts, such as pilot helmet and ejection seat, now of composite materials. The radar cross section of modern jets can never be below a minimum undetectable value for many reasons. Internal bay on opening gives away position. The engine exhaust from rear is metal. And pilot face can not be covered, and is at least as big as pigeon on radar!
