Worked on Mini 2016. You can see that my Mini had like that peeling problem and simply coating wax on it did not work. I cleaned it with sensha moulding cleaner then did glass coating on it. Worked!!! I have plenty left so I will give a shot with my Mecs as well. Amazing product.

Great to have this famous Japanese brand in Australia!
I could not tell how these moulding parts were dirty by looking but they got solid black looks after using this cleaner. I should try moulding crystal to make them even deep black gloss look.

Side moulding got white wax stains and they could not clean with car shampoo. SENSHA cleaner works great.

Whitening not occurring anymore. Great item

I was so struggle to clean wax marks on molding but this cleaner cleaned them greatly. The attached sponge looks very special. I will try molding glass coating to keep this.
