I am in the process of gilding a large out door oak sign with deep V grooved lettering (aprox. 6” high lettering & 10mm deep).
The sign will be semi protected from all weathers but still subject to much rain and wind, high enough to be out of reach of fingers though. Would there be any recommendations for a coating over the gold leaf to protect it? I have come across the use of shellac, would this be a good idea or not?
Thanks for your help.
Kind regards, John
