thank you very much, my friends!
your comments are very supportive!
to tell the truth, a good friend of mine

, told me that the lamination is not appropriate for british prop, as it was more a german feature... so the prop is currently been washed anew with alcohol and it is being repainted... I'll show you some picture soon.,
nevertheless, the pencil method is great, it gives you a lot of freedom on what colour you want to stress, resulting in different wood shades, and it very easy to control! you should defintely give it a try!
ciao
