I noticed that the dash and trim are discolored from oxidation. I recently bought a used cart. It looked like yours. I used Maguire ceramic trim repair. It looks almost new. And it isn’t just a coating. It penetrates the oxidized layer.
There are so many products with similar appearance on the market that it is really difficult to distinguish between good and bad ones. I bought the 48V 105Ah of Vatrer Power a few days ago, and it works well now. It is still under observation. They are so similar that even the screen is identical.
