restore blackness to outside plastics

[Lukexc702002]

Hello, I am new to the forum and I have a 2002 xc70 ocean race edition, there is plastic of the outside of the car around the fenders, bumpers, and rockers, this has faded to a weird navy blue, i think it was either once black or a very dark navy blue. Is there anyway to restore the blackness to these plastics or maybe make them a bit darker?

I have just started darkening my 2001 V70 XC bumper plastic with a heat gun and so far so good. Lots of videos on youtube explain the process in detail.
