To BVC500 :
Dashboard is too small and intricate to apply masks.
For the moment I work to do the drawings as precise as possible. Final products will be only decals.
Like said on kbx's topic, special colours are a trap, because they are very difficult to match with paint used by the builder on the main body.
So, I think to put on the sheet only basic colours like silver, white, black and red.
For special colours (metallics, ivory,...), I study the option to use clear or white decals as bases for custom paint.
If idea is interesting, I must check if decals could resist to several layers of paint and varnish.
Will they be usable after all this paint job ?...I don't know.
