Well, a couple of months ago I purchased a used silver KP. With only 8000 actuations and a price that was too good to ignore I decided to go for it since, even if extremely satisfied with my K-70, I have always loved the "retro" look of the KP, especially the silver one.
It became instantly my "only" camera! The level of customization you can achieve is unbelievable, and the third wheel is a game changer for me. Actually I can take pictures and change all the settings I need without ever accessing the menu and keeping my eye in the viewfinder - unbelievable! That is exactly what I was looking for and I got so used to it so quickly that it is now my camera of choice almost any time.
The only "defect" of the camera I purchased was that its previous owner kept it in a too tight bag, so with time the silver paint on the angled edges of the top (plastic, unfortunately) flash housing came off. I knew that before purchasing (it was the main reason of the lower cost) and I believe I could leave with it, but I was lying to myself and each time I looked at the camera those black borders were disturbing me. I never cared about such details on my other cameras, maybe because I have always had black bodies, but on this otherwise shiny and gourgeous KP the sight of those black scratches were really disturbing me.
I tried to cover them with silver markers and apparently it almost worked, but it was enough to use the camera once and the marker's paint came off as well

. I thought of using metallic gray paint specific for plastic but I was reclutant since if the color was not exactly the same one I was likely to do a mess that couldn't be cleaned later without damaging the original color.
In the end, I came across the ad of this spray paint which is normally used to customize cars, bikes and other stuff, and I was hooked. It is not exactly a paint, it is a sort of liquid plastic that you spray over the object you want to change color to and after it dries up it forms a wrap on it. By adding several layers of spray (letting it dry each time) the color evens and this wrap becomes a scratch-resistant skin that protects your object and that you can simply peel off when you want (or if the result are not satisfacory to your taste) without damaging the original paint beneath and leaving it as new.
I am attaching the final result. I have to say that I am impressed! The color is only slightly darker than the original body paint and the finish is exactly the same. The overall look is quite pleasant to my eye and I thought to share my experience in the event that someone else wants to experiment (many colors are available for thos who like colorful looks).
As soon as the new flagship is out and the price of new KP bodies hopefully drops I'm going to buy a second silver one and I'm going to wrap it up from the beginning so that I can use it without fear of damaging the original paint!
