HELP!!! Leather bucket seats

[M-A8]

So guys, I dont really know much about it so I would really appreciate if you could share your experience and knowledge.

Yesterday I went to pick up a 57plate RS4 for my mate with the proper bucket seats.
Car has only 57k on the clock, but sides are worn out as you would expect from this type of seat.

He is as an@l as me and he want to have it done properly.

We've heard about rubberized spray which covers the textile with some liquid rubber leather lookalike but non of us ever used it or seen it in action.

But, it's all about the look of it afterwards and life especially.

Guys, any honest and serious advice will be greatly appreciated.

What we need to know is if the spray on stuff is really good and if it does last long.

If replacing the sides with new leather (bottom part only) we would appreciate any recommended guys to do the job and if you know more less the cost of this job per seat that would be even better.

Ideally anyone located in London, Kent, Essex, Sussex, basically London area and anything within 60miles from M25.

Many many many Thanks guys

PS, just looked at the pictures again and passenger seat isn't that bad.
The driver's seat actually would need sides done on the top part as well.
