I had the same issue with mine. What colour are your trims? You have a couple of options, buy a good second hand set, get them aqua dipped or there's also a guy on M3 cutters called lovatt who sprays them, he's supposed to be very good. But it might be costly with the added vat due to brexit.

I originally changed mine for a second hand set, but they didn't match my smg and steering wheel surround and my ocd got the better of me. I came across another forum where someone used 3M wrap that matched titan shadow, so I said I'd check for myself and I was very happy with the results.
