I have previously posted on the efficacy of Monitor Audio "Sheer Brilliance" Lacquer Polish. An Auto Glym product. Stated to be designed to replenish high gloss lacquer finish on all so finished loudspeakers.
Carefully applied on my chosen Orange Meridian collection it is a perfect application. I have no connection to AutomGlym.
Thanks for this, I had missed your previous post. I bet those volcanic orange DSPs look fabulous after a good polish!
And +1 on the advice to avoid any products with silicone, you really don’t want that around if you ever need a respray.
