It is off course a question of taste......I am from the other group of modelers, means I try to make a model as realistic like the original as possible. Therefore I am trying not to leave any char where ever possible - maybe therefore I have to sand on my model so much in moment....Hi Uwe. Good question. On my particular model, yes, I plan to leave the char as a decorative color contrast. That is why some of the parts in this assembly were CNC while others were laser cut. It should blend nicely with the edges of the planks.
