Sharpie did not work well on mine. In the end I junked the whole setup when input buckets in and used BMW receivers… sorry.

I’d also tried Gtechniq trim restorer, slight improvement but still like one of those old white dog poos.

Yeah, I think some of these videos online are probably not of the first attempts. I gently heated mine but the point at which it starts to look crap happens so quickly that all you're left with is something that needs replacing.

Tried this on mine as well - did nothing I don't want to risk a heat gun incase I melt them.
