You are using too much manganese additive. Back off about 1/3. How much are you using now, ounces additive per gallon of fuel?
The MMT makes the orange color on the plug and the too-hot plug ceramic fires the metallic to a shiny glaze, same as coloring or glazing pottery, when it goes in the furnace it looks dull and flat and after "firing the glaze" it comes out shiny because the heat melts the metallic and it flows out smooth and shiny.
With MMT it is normal to see a light tan color, but when it starts looking a wet brick orange color it is an indication of too much.
