From what i have read it's not the actual mixing of the components that is a problem, it's getting hold of the correct pigmentation for the correct shading, in this case "shark grey" pigment would, like all pigments be made up from a number of addatives from a number of suppliers.
I work in the plastics industry which use tremendous amounts of pigment and work closely with pigment manufactures from around the world, sometimes it is very difficult to hold onto a particular colour because of pigmentation supply problems, a colour that has been holding for years is all of a sudden no longer available, and to make matters worse there are many "copy" companies that try to "mirror match" a particular colour but it is never ever an exact match as the original, metalics are a particular problem.
If Peugot could gaurantee that a pigment from a new supplier would be a total colour match they would not be suspending the shark grey option, just closing down a pigment blending extruder for a few days, then doing a new start up would have a massive impact on colour shading, to move too a complete new supplier that then in turn also delt with different suppliers and used totaly different blending systems would be out of the question, this is why, until they can, with confidence match the pigment, Peugot have to suspend shark grey, they really have no choice, in fact they are doing the right thing.
As for damaging a panel that needs a full "lick" of paint, well hopefuly there is sufficient stock of authentic pigment, the thing to remember is this, how many people go to a dealer for repairs, most insurance companies use outside repairers, who mix their own paint or buy from a paint supplier anyway, so in that sense your not getting a true shark grey colour anyway.
This pigment shortage will only affect someone who wants to purchase a new car in that colour right now or insists to an insurance company that a dealer repairs any damaged paintwork, however If they are prepared to accept an "after colour", for any repair work then all will be fine, again though as long as the owner accepts the colour match and shading !
Another angle on this though issue is this, would a prospective buyer looking for a used RCZ avoid shark grey purely because of this "problem" , the colour may be "unique" for all the wrong reasons. :eusa-think:
My advice, go for Opal white, you know it makes sense, and it's nicer :lol:
