I believe the 'chrome' is often a very thin metal layer so if you sand the surface it may damage it enough to start peeling off. Not done it myself before but I would suggest using a self-etching primer without sanding (after cleaning the parts).
No doubt there will be many YouTube videos on stripping chrome if you decide to go that way.

I would de-chrome it with spray for baking oven, quick and easy. The aggressive one where is stated on the can "Do not use on painted surfaces." 😉

Thank you very much for your reply, Mates.
I heared about the Oven Spray. I checked my thinners and discovered a Tamiya Laquer thinner (yellow cap). I let the chrome parts over night in this and....taaa daaaaaa....all gone and easy to scrub off👍
Thanks again for your hints and clues. ✌️👍
